Reverse implied odds, as others said we can be behind on a club to better combo draws which would make better flushes, 8x or Tx losing to better boats etc. I'm not actually saying necessarily fold turn fwiw.
It would be an impressive fold on the turn but mainly because his range is so narrow I can see why many people advocate this play...his range basically consists of JJ, KQcc, AJ, 88 (probably in that order of likelihood imo). It would definitely be nice to get away with losing just around 20% of your stack as opposed to 50% - and we have genuine concerns that we might not even be good if our flush comes in on the river (in which case we'd bust since we'd obv be snap-calling).
I'd also definitely side with the guys who say bet on the slightly bigger side...140 seems way too cheap a price to be giving and builds a smaller pot the times when we want to be barreling what is perceived by hero to be the best made hand on future streets.
