As far as I can tell plex only wants separate folders for different kinds of media and file names that give at least some clue to what it is. Plex is much more lax.
The problem with Plex is that is has a very opinionated system that ignores how things are in real life.
One example I can point to is Stargate SG-1. Episode 1 is a two parter and depending on who you ask it's either Episode 1 and 2 or Episode 1 which causes all subsequent episode numbers to be thrown off by 1 depending on how you count.
This confusion is further complicated by the release order on DVD/Bluray, the order of airing, and the fact that all of these things can be different in different regions of the world.

And that's just one show.
