Well, at least it's evident that White has no repertoire (pretty every serious 1. Nf3 player knows that, except if s/he goes for KIA, c4 has to be played first, even if it's a sac like in the Reti or QGA, where White has enough comp) and just tried to play good-looking developing moves like you said. But in some cases, they don't work.
And it's the case where playing Nc3 early is suboptimal because, if White makes another 'natural' move 3. d4, he ends up playing an analogue of Queen's Gambit Refused but with a pawn on c2 instead of c4, with Black first bringing the LSB out to f5 (which he can do because Qd1-b3xb7 isn't threatened with the pawn stuck on c2) and then being able to cement the centre by e6 and to meet Bg5 by Nbd7, and also to support d5 even more by c6 in the Semi-Slav fashion.
White is better off playing in the KIA spirit - 3. d3 to prepare e4, and blocking the LSB and having to fiachetto it, or 3. g3 immediately with the same idea, whereas Black will develop normally by Nc6 and e5.
But I think it's rare to see someone who plays 1. Nf3 Nf6 2. Nc3 actually know his trade and play 3. d3 or 3. g3. That's because the best square for Queen's knight in KIA is d2 (not c3), where it's ready for the Nd2-f1-e3 manoeuvre and also prevents the queen exchange after the pawn exchange on e4. So a serious KIA player just wouldn't put the knight on c3. (I play 2. c4 after 1. Nf3 so can't tell much about KIA.)
