Posting or Rising to the Trot – Podcast

You are a luck person if you have iTunes. Today I subscribed to the podcast channel “Daily Strides”. As far as I understand, the instructor delivers several such podcasts every week. On the podcast below she speaks about rising trot. She touched all my mistakes; using the upper body etc, but I found interesting her opinion about the “up-down” instruction. She says it’s wrong, because it creates exactly this problem. Better, she advises instructors to use the “one-two” instruction instead.

And I don’t get the difference here: why would “up-down-up-down” specifically makes me makes all these mistakes, while “one-two-one-two” works better? Any ideas?
