I guess I was right about Dimensions that didn't branch off of the main timeline.

So Dimension 23 is probably a dimension that didn't branch off the main timeline.

Gwen 10 is probably the same or it might have branched off at an earlier time.

Anyway it seems like they use "Alternate Timeline" if the dimension branched off from Ben's reality.

And they use Alternate Dimension for those that didn't branch off from Ben's reality and those that did. So when they mention Alternate Timeline, it's already clear. And when they mention Alternate Dimensions, then it could either be a different dimension or an alternate timeline.
