Yes, I believe it's shoulder. However, if the command is to trot at A, I will start preparing myself and the horse for the transition in the corner before. You want to avoid a lazy transition (a horse that walks faster, often laterally, for a few steps before trotting) and an ambush transition as I call it-the horse seems to be quite surprised by the command and jerks into the gait.
