The more I watch this technique, the more I like it.
She should get some sort of bonus for straightening before landing.

I really like the Gymnastics Canada WAG Aspire program for talented young gymnasts.
The Aspire Camps are great too.
You can check out the 2017-2018 ASPIRE PROGRAM MANUAL online for free, if you like.
There is one error on page 15.
Of course the path of the Centre of Gravity starts tangent to the point of release. If you let go of the Bar when the C of G reaches horizontal you’d best be doing a Geinger.
If you release with hips above horizontal as required by that Aspire graphic there’s a very good chance you’ll land on the Bar.
The video linked from page 15 is correct, however.
The gymnast could apply a force to the Bar on release to either pitch-out or pull-in the Centre of Mass. Pulling-in can result in hitting the Bar.

It’s usually a mistake to copy the technique of the best athlete that ever lived. What worked for Usain Bolt might not work for you. He became one of the best in the world with much less training than his competitors.
That said, this is an interesting video looking at technique and efficiency.

There’s an interesting thread on Facebook on this topic.
Most would consider cast handstand in a hollow / stretched position throughout as ideal. Nick Blanton mentioned this illustration from Championship Gymnastics.
It’s possible to do that technique. In fact it’s fairly easy on Parallel Bars as a swing handstand.
But I’m personally a very happy coach if the gymnast can lead with the heels (arch) to horizontal, then change the body position to hollow / stretched.
The ultimate would be perfectly straight through hips / trunk once leaving the rail. That’s difficult. The gymnast would likely be strong enough to do planche press without swing.
