I think they are doing different things. There are things you want to
happen on each buffer when and once it becomes a "LaTeX buffer". Setting
buffer-local variables comes to mind.

And to nitpick a bit more: it doesn't happen when a LaTeX file is loaded,
but when LaTeX mode is "switched on", that can happen in other occassions
too (when creating a new buffer you know it will be LaTeX, but you can
also switch the mode on and off; LaTeX isn't a good example for the second).
