hmmmm….I haven’t done a pattern like this before, so it’s not easy for me to understand. But judging from the picture I could find, the front of the top has like a slit opening with a tie closure, right? Not seeing the other steps, my guess would be that the yoke extends past the front but will eventually be folded back on top of itself to give the yoke a folded finished edge at the opening. For me, I would just continue. I’ve also been there where I’m doing something that isn’t quite clear to me but once I have the physical piece in front of me and I’m going through it, it eventually becomes clearer in a later step.
