Looking at the video, the question I'd ask is "Where's the foam?"
"It's behiiiinnnd yoouuu...!" (Sorry, it's pantomime season here in the UK 😁)
As Clay says, you're not extending, also your front arm is blocking your twist, so you can't look back to the foam.
You can still practise compressing and extending on a surf skate in the flats, but it's not as good as in a bowl.
You could also do it on a Bosu ball and work on lifting your front elbow and putting it in your back pocket.

Michael Van Mil Sorry, Pantomime is a traditional British Christmas theatre show for kids, performing stories like Cinderella, Aladdin etc.
The villain is hiding behind a bush as the hero is on stage and the audience calls out "He's behind you!"
The villain ducks as the hero turns round, so the hero says "Oh no he isn't!" to which the audience responds "Oh yes he is!!" 😁
Ahem, anyway, yes, work on the front arm 😉
