Investors often asked YC companies themselves, "What company is hot?" instead of judging things on their own.
If you have booths with demos, having more investors gathered near one booth might end up as signaling to other investors that this is the "hot" one of the batch, which results in more gathering. And where the investors cluster could have been a random event, or the location of the booth was better, etc. I can imagine founders spending all their time being big and splashy with swag and posters.
