Back Thumb Palm's enemy:-Gravity

[Lord Magic]

Simple question, I just want to know of anyone knows how to get into a back thumb palm while the hand is hanging seemingly idle on one side.
The scenario is that I have false transferred a coin to my left hand. Meaning, the coin is still in my right hand. Then I am going to say something regarding the coin and just sime patter. And that is when my right hand will be trying to achieve a back thumb palm. All the methods I know work only when the side of your hand is parallel with the floor.
So, any help?

Also, if anyone knows how to get away with the simple back thumb palm motions without attracting attention to that hand, HELP MOI PLEASE.
Effect intended for small groups (4-5 people)...PMs with help welcome.

Most of the time I get into a thumb palm in the process of passing the coin from one hand to the other. It's all one move. I don't do a false transfer, then thumb palm it. I palm it as I do the false transfer.

Most of the time I get into a back thumb palm from JW/Cigar grip but in reality I use the back palm or Goshman pinch rather than a thumb back palm. Take a ;look at the combination vanish in this video.

Thanks so much.
The video is amazing. These kinda videos either start making me feel motivated abt what I could achieve with practice...or sometimes they make me feel depressed abt the current state of my sleight!

And the thing was that my false transfer looked better than the alternative. But I guess there's no shortcut. Back to practising my "Back-thumb-palm-false-transfer" I guess.
