I don't see that.The difference is that there is not sufficient space to support an additional stand-by and lightning lane queue for separate experiences.
Here's the super wide queues for Stand-by and LL.
However, they do narrow. The question is can they narrow down into four lines?
Here is the one side, which pinches people down from a very wide queue to just side-by-side. It has railing that comes out of nowhere to do the pinching. It and that trashcan can move. This would create two LL lanes: one for show A and one for show B.
And this side has no pinching at all, it stays very wide. Easy to create a line for show A and one for show B.
