So how does it work exactly?
If he it's February 1st in World A, then next time he goes to sleep and wakes up it's still February 1st but in World B? Or would it be February 2nd? (So he loses a day in each world)
Cuz if he gets to live every day in each world, and they are sufficiently similar (which seems that way), then he could take some advantage of the situation (of course, he could be taking advantage of a "fake world").
It's gonna be revealed in the series finale that both worlds are fake, and he is just in a comma the entire time...
