PLEASE don’t take this as unkind criticism. Since you posted it here where discussion of rotational falls is taking place, it seems appropriate to comment on likely causes. First, I wouldn’t consider it a rotational fall. But if you watch closely, you’re dropping your right hand as early as the turn and it stays low at take off. Then, your body is parallel to the horse’s neck long before she can get her leading (RF) leg out of the way. Your low inside hand around the turn allowed the mare to drop her inside shoulder, making her heavy on the right front. With a shorter take off distance such as this, even if she were ideally balanced, it’s best to sit tall to the base, release out of hand if possible and don’t close your hip angle any more than necessary (any more than the horse automatically closes it for you). When you jump up the neck before the front legs are folded and out of the way, you make it much harder, and sometimes impossible, for the legs (especially the leading leg, since it’s the second to fold) to fold clear of the top rail as your body weight adds to the load on the horse’s forehand. Another problem with jumping up the neck is that the horse pushes off the ground with enough force to clear the jump with you in the middle of the tack, or comparably so, compared to laying on the neck. Adding excess weight to the front end at a jump after “calculations” have already been made can mean that there just isn’t enough “oomph” to tuck up the forelimbs under an additional X number of pounds.
The left front was going to clear just fine, so my guess is that she knew exactly where that top rail was, but being heavy on her right side, with her right shoulder dropped and then an “eager” release on your part added up to make her unable to get the right front clear.

No offense taken! That makes quite a bit of sense and is very possibly the reason for the tumble. I definitely am not always perfect and this was a difficult exercise with lots of room for error, a few of which I probably made. 
Again, it’s not a rotational fall as she never flipped end over end and I understand that. What I was originally trying to convey is that the way in which she made contact the fence could likely have resulted in a rotational fall had we been jumping an immovable object and that wasn’t because of a horse that has a naturally dangerous jumping form, nor was it a completely frightening distance, which is what the OP originally had inquired about.
