I don't see what's wrong with the picture.  Can you be specific?

y must always be split into cells, regardless of whether you use & or &: .  The difference comes in whether you collect the results before applying them to u .

Written at the top of the page:
Applies verb v to each argument in its entirety, and then applies verb u to the result(s) of v

The diagram says about &: (bottom to top):

* split y into cell
* apply v to each cell

Nice day!
