Yes, it can. There are settings in your My Disney Experience account where you can select which "friends" can share Memory Maker photos with you. I know on a recent trip with various WDWMagic members, a bunch of my ride pictures and videos were accessible in a fellow traveler's Memory Maker account.
Now, I'm not certain if that means they are automatically included if you purchased the full package. I'd have to double check with
@Monty on that one.
