I don't like the weave look, I like to see the definition of the valley. Yes, having the ridge helps to keep water from undercutting the opposite side. If the sheds running to the valley are more or less equal the water will meet and sort of cancel the issue.

It looks OK to me but they could do a better job of staggering and I like to see at least a couple inches of metal to keep the valley clean.
