No interactions present.
it does look like it from the way it is positioned on the branch
There seem to be 2 factors involved here. 1) the branches near the mass of material have been pruned and there has been a fair amount of new thin growth as a consequence. 2) twigs have either collected in or, as suggested above, been placed in the new growth giving the impression of a witches' broom.
