I am having trouble visualizing that. But, do you know the footfall order for canter? For a left lead , it's right rear (ONE), left rear and right front at exactly the same time (TWO ) and left front (THREE), and a brief moment of suspension, the the same order all over again.
So, your horse is putting down his right rear first, then lifting it off the ground just as the left rear comes forward and to the ground. So, are you saying that he puts it in front of where the right rear USED to be ? I think that would be pretty normal, unless you mean he really reaches way over the midsection to the opposite side.
