No it doesn't, taking 1 minute to create each world is worse than baseline 2-C, the fact that he can't create all of those at once means he ain't 2-A, simple.
Just to clear, the size of the worlds don't matter, than being finite or infinite in size does not change anything, only the quantity created at once, he clearly only creates one world every time so he is at best 2-C
Also, that's the definition of countably infinite, reaching infinite by counting for a infinite time, i am just explaining you what 2-A means and why the player ain't reaching it by creating 3 universes per dream
