I can't find anything that refers to that in any other way than crossing centre strokes. Look [here][1] for reference.

However there is a pretty substantial glossary of type terms [here][2] that calls the meeting point between letters a Vertex. The fact that this comprehensive list doesn't reference the crossing centre strokes as having a specific term suggests that there isn't one.


Looking into it further, it seems that fonts with those characteristics aren't necessarily identified by the cross in the strokes, but may actually be identified by the amount of upper terminals in the 'w' as [Identifont][3] does:

Hope these help.
