Further examination of the branches shows no damage. All the leaves are
there and arranged haphazardly. It may be, as another person said, an
artifact of the rapid growth of the vines, as the tips of the vines are
more regular, although not as regular as your plants.

The dichotomously branched stems seem to make it through Ontario winters
