From what I understand this is all to make multi-tasking as easy and fast as possible.
You know how accessing the XMB while playing a PS3 game is extremely slow? The game is using up all the resources which is why the XMB is so low. With the PS4, one GPU will be dedicated to XMB/apps/etc while the other more powerful one is reserved for games only. This would make switching between an App and a game smooth as butter. This is exactly what the rumor from VG247 said about accessing the PS Store while in-game.
Sounds very promising.
