Alec Torelli went north. The TV graphics has his chips wrong and he went from one $5k chip to two $5k chips. There is a twitch video with the entire session: Someone in the comments of Doug Polk's video, who is a friend of Wolf, found all the details we need to know.
This is an excellent analysis of what happened:

Hey Doug, the raw live stream footage of this session is still available on twitch.
https://www.twitch.tv/videos/58450160 I went through and did some analysis of it. I'll list the interesting pieces here with timestamps. Full disclosure, Dan Wolf is a friend of mine. 02:38:19 - This is the first hand of the post-dinner session, so Torelli has just sat down and gotten his chips set up. He has a single silver chip on the table, nonetheless it has already taken its position towards the back and to the side of his stack. There is a gap that would allow some of the people at the table to see it, although certainly the people to his left would still have some difficulty. Over the next 20 minutes or so any time they show Torelli's stack that gap between his orange and green stacks gets a little smaller and smaller (for example 02:51:59,) until: 03:01:58 - We see Torelli finally push his orange stack the whole way against his green, completely covering his silver chip. Notably Dan has not yet sat down at the table at this point. 03:05:39 - Dan makes his, ahem, entrance and there's that silver chip tucked away. Completely hidden from his view as seen at 03:06:21 from his angle. And that's exactly where it remains for the entire time Dan is at the table until the hand in question happens. Everything stays this way until: 04:24:00 - Torelli loses a big pot to Tilly, putting him down a little over 10k for the session. His silver is still covered by the oranges 04:25:14 - This is one of the most interesting pieces of the video. This is the exact time we can see Torelli reaching into his jacket pocket to pull out the second silver chip. Unfortunately the camera cuts away before we see him pull it out, but the next time we can see his chips he has two silvers. The second one goes right on top of the first one, notably still covered up by his other stacks even though he's clearly now interacted with them and could have moved them out front. Also worth noting, even though players are supposed to notify the PNIA production crew when they're adding on (so the chip graphs can be updated accurately,) Alec doesn't tell anyone. Neither the crew or the players at the table. For the rest of the time from now until the hand in question the count of his stack on the graphics is $5k off. 04:25:41 - The next view of Torelli's chips, an ariel view, showing the two silver chips. Although is it admittedly a little hard to say conclusively that there are two there. 04:29:35 - The next clear view of Torelli's chips, clearly showing the second silver on top of the first, both tucked completely behind his oranges and greens 04:30:57 - The next time we see a graphic of Torelli's chip count, showing that it is not updated to reflect his added $5k. 05:09:52 - This is the last hand Torelli wins before the hand in question. In the PNIA video we see him try to justify himself to the floor by saying that he had just won a hand and put those orange chips in the way of his silvers as a result of it. But this was a small pot that netted him 0 orange chips, and also left his orange stack exactly where it had already been. That is, in front of his silver chips. 05:15:00 - The hand in question finally starts. Notably Torelli's chip count graph is still inaccurate, and the announcers (once they catch up with the action) are also unaware about the true size of Torelli's stack and mention that they must have missed the rebuy. Overall quite a few interesting bits there. You can draw your own conclusions from these pieces of evidence, such as they are.
Again, go find this is the comments section of Doug Polk's video on Alec Torelli. He went North for $5k and hid that $5k from the table. Not even the dealer could see it. Look closely!
