In other words, we're not putting words in the GDC's mouth. We're taking what they say at face value. Because they don't specify that appendages in the process of being deployed are exempt from contiguity checks, we can reasonably assume that an H or a Y that simply rotates downwards will at some point be discontiguous outside the frame perimeter. Therefore, it becomes illegal at that time, drawing a foul.
