Dimension 23 is a seperate timeline. They probably just used the wrong word in Store 23. According to paradox, ben 23's timeline, and all the others, branched off of the main one because of events that happened differently. Dimensions are not the same as alternate universes though. Diagon's dimension, the null void, and Ledgerdomain are all sperate plains of reality that exist in each alternate timeline. So yeah, your pretty much right.
