This seems a bit odd for a palatable, unarmoured plant that has
developed in areas with browsing animals - and most species of
Vitis did! But plants are sometimes odd.

Perhaps there is a growth point at which the branch is too thick to 'browse'
and this is the size at which it is vulnerable to pruning?
Young shoots are easily lost but thicker stems not?
Again perhaps the 'bleeding' is not that serious to a wild vine where much
of the plant is inside the tangle or out of reach - but more of a problem
where the vine is limited to one or two main stems and pruned to minimise
extraneous growth and focus on a few leaves and large bunches of fruit?
