That looks a bit more complicated than a W wing due to the
two candidate 4s in b2c4, or am I mistaken? It still works
of course!

I think that's called a grouped strong link. It's not that complicated if you train yourself to look for grouped links in addition to regular. First time I saw one I questioned it, "hey that's not a strong link." (It's easy to learn that way!)
