I don't understand why if by default it´s suggested that select / hotkey be the same button

Having a dedicated hotkey button is the recommendation as far as the libretro project is concerned, and it will configure this automatically with most controllers sold commercially. Using an already-in-use button is only a workaround for the few users who actually can't afford this. Retropie might be doing other recommendation though, i don't know.

Perhaps it would be convenient to add this information...

Well, that's not exactly a frequently asked question tbh, i think you are the first person bringing this up since i started working on this core over a decade ago, but i have seen similar issues where the user couldn't add credits in certain games (the coin input in arcade cabinets is kind of a hold mecanism). Also, this is more of a retroarch behavior than a core problem. Adding something about this in the doc might be a good idea though, thanks for the suggestion.
