You're taking "access" too literally. Verk means that(if I follow correctly) that there are infinite realities occurring with infinite permutations of every possible outcome of every possible decision that one would experience.
However we can only know and experience that path which we have taken.
Think of it an an infinitely wide tournament bracket... but instead of narrowing down to a final outcome... all that happens when in regards to the "win/loss" when a decision is made is that it shifts the current reality to the next, "consecutive" branch.
Or even better think of reality as a flow chart(again, infinitely wide with infinite permutations)... just because you make the "yes/no" decision on the flow chart, the other option still exists, we just don't "experience" it.
Stoned rambling, so I might not make sense, but I think I did OK.
