Thank you for sharing, this is very interesting, I should try this on my leggy plumerias.
I had a 3 feet tall last year that I cut up into 3 pieces and rooted all 3 last year, the problem is, I don't think I will see the bloom this year.
What I like about this pruning process, is it leaves some of the Branches from last years growth untouched, which could result to blooms this year. Also pruning probably encourages more branching giving it a fuller look. Hmmmm I will definitely try this on one of my no ID plummies or seedlings.
