I have modified the page to respond to these observations. Others may

Since it objectively works in u, probably what you mean is that there's an
efficiency case for doing it in v instead, or that Z: can have some surprises
in u. Why not state that?
Just the case from the other way is a bit more annoying to do in v
0 {{y[1 Z:y>10}} F.. + i.10
15
vs.
NB. explicit code to avoid repeating op
0 [ F.. (4 : ('r=.x+y';'1 Z: r>10';'r')) i.10
15
NB. forgot the goal here and repeated op anyway
0 [ F.. (+[1 Z: [: >&10 +) i.10
15
0 [ F.. ([: ([[1 Z: >&10) +) i.10
15

I updated the nuvoc Vocabulary/fcap page to state that Z: in u does
not make sense for fold single.
I think this is correct. Let me know if I'm off my rocker here.
Thanks,
