and your nose!
It is not the jump in improves, its the landing. The horse in question jumped every jump with a good foot in between and would land with both front feet slammed into the ground and head as high as could be. With the martingale he does not have the ability to land in whatever form he likes, he has to actually keep himself together or he will get a nice snatch of the nose. I am sure it has other uses for situation, but one use for it is NOT TO KEEP THE HORSE IN FRAME as many many many of the local no name trainer try to embed in their unknowable students. OK done now since I think I am taking this thread away from its original purpose. 
I rarely see either martingale adjusted properly.
Standing martingales are almost always adjusted way too short. The standing should be able to touch the throat when the horse’s head is in the neutral position. It should only effect the horse when the head is way out of position. These short adjustments will often teach/allow a horse to lean against the pressure and use it to balance themselves, instead of using self carriage and proper haunch engagement. I see this way too often.
Runnings are also often adjusted too tightly. Again, the rings should touch the throat. They should only effect the reins if the head is way out of position. You should rarely be able to “feel” the martingale in normal riding. I use a sliding running martingale (hard to find!) that allows the ring attachment to slide through the ring at the chest. That way, you are able to make sharp turns without the running interfering.
For me, both martingales are only a precautionary device and should never be considered a “training aid”.

OK, that makes more sense.
In the earlier post it sounded to me like he was jamming his head down to the ground as well as his legs.
Thowing his head up on landing sounds more like he is trying to spit out the bit and increase his speed, a polite way of saying trying to run off, or that he has some back or leg pain.
At any rate, it is an attempt at disobedience by getting his head much higher than normal and therefor the bit in some attitude that he thinks gives him an advantage and that is what a standing is for.
