Am I the only one who thinks that the barrier has no width, while at the same time, before fighting Asgore, it is shown to have.

Here's the problem: There is the gate you enter before fighting Asgore. When you enter the same room after fighting Asriel, there is a patch of light and green. The same kind Flowey is on when you meet him. Then there is the exit.

Normally, the barrier should stretch between that two doors. But, when you fight Flowey, you end up on that green patch. From there you can go forward (and only forward), and presumably reach the surface. By the way, weren't you supposed to be able to cross the barrier from the outside? Guess not.
