Here is a 'Y' that is a little further along. You can easily see the primary 'Y' and the secondary 'Y's.

What Louise is talking about is when a brug is about to bloom or it begins a 'Y', it will form what are called subequal leaves. You can see one in this pic - directly above the primary 'Y' spot (and kinda just to the left of the right secondary 'Y'). You can see where the right side of that leave comes down the leaf stem a little further than the left side.
