You can't shoulder a dummy runner in the head either, so I don't think it really changes anything, it's still foul play.
I feel like had the pass not been forward Bierne might have had time to get low & get an arm in a position to wrap. Being such a big guy he might still have been too high to avoid a Yellow but might have done enough to take the Red out of the equation.
