Almost doesn't matter if he is confusing it. The game can load data into RAM in the background. Perhaps during the intial loading screens (picking save files etc) and when you first enter said world. Once everything is dumped into RAM you're good to go.
More RAM is NEVER a bad thing except in terms of cost (and maybe power, but that's almost negligible in this case).
