Thoughts on Piano Key Touch Techniques

[somersault touch]

In this video, the runner tripped over the beam, but she instinctively somersaulted forward, winning the championship. It stimulates me the think that one kind of touch technique is based on the same principle. Your drop your hands and when they touch the keys, you immediately let the fingers roll forward, which creates a downward momentum to press down the keys. 

This is kind of advanced touch technique. [Youtuber ..] explains it very well in his Youtube video.

It can also cure a problem corrected by Dorothy Taubman in a video. The problem is that the player already press down the keys before touching the keys.
