I didn't know that. (I assume you're talking about multiple haplogroups that
are shown on the same vertical line). The YCC site mentions a more mechanical
"rule" that appears to be a page layout algorithm:
"The tree was drawn as asymmetrically as possible by sorting the descendants
of each interior node so that the bottom-most descendant had the greatest
number of immediate descendants."
I'm trying to think through whether your statement about relatedness follows
as a natural consequence of the page layout rule. Are you saying that we would
not expect to see a join of G and I, or M and P?
