Sorry mate, but IMO that's not a hook. The cyclist was filtering through on the curb (blind) side, so shares the bulk of the blame.
The kind of mishap is an all too common event when filtering too close to the intersection.
As I define it, a right (left) hook is when the passing vehicle turns before properly clearing and completing the pass.
In any case, nobody got hurt, and folks stayed civil, which is about as good an outcome anyone can hope for.
