Here´s why and how I did spotted those Yen´s yesterday using ChfYen for it – triple tree.
It can run more complex as that if it wants to but another x would come anyway first. In that top there is potentially A and B in that are where triple tree ends.
I do not have this example yet in the site but if you count them, you simple have those same 11 waves in it and 2 of them are X´s.
