Are you kidding? He's embellishing all over the place! He's also giving her time for some too.
That's a gross exaggeration, a few toe taps on the upbeat that never
get in the way. I think we can forgive that in an exhibition.
Yes, he gives her time, and why not? That isn't back leading from her.
You can see that amongst experienced dancers in WCS and the various
jive style dances. Salsa and Latin dances even more so at times.
If by embellishment" you mean high boleos and ganchos, then no. But that isn't the limit of what can be an embellishment, and Vidort does quite a bit in this video. I wouldn't want to try to count the number of taps, flicks, leg lifts, etc he did with the free leg that were what I'd call embellishments (ie: not required for the lead or execution of the moves done together as a couple)
But there is an off-axis carousel but then again, it's an exhibition.
It's still a very different dance from all the explanations being bandied
about in this thread.
As to her powering the molinete, it's hard to tell from a video just how much the follower is or isnt' doing. I'd say that since he is stepping with her, she has little need of adding power. If he were pivoting, she would need more.
nor him heave her about. Any pivot is a result of the power of chest rotation,
my partner is already with me - she is always with me.
