hmmm Interesting I'll give that a go!
I did try just cutting the top off and spraying the naked cut (as opposed
to just staying the leaves). BUt yeah your suggestion might work

We kill off a lot of roots for privet and such by cutting the stem/trunk
and painting stump(small 1/2" paintbrush) or cut vines (small artists
brush).

I used the bottle of roundup on a vine that kept reoccuring. Figured
that we were not getting enough poison back into the roots but the cut
and paint method.
