Spurring new sps growth

[spawn]

I don't know if anyone else has tried this, but a little while ago after trimming a sps branch of a "Green slimer" acro I noticed that quickly 2 new branches started from the spot. So I wondered if I trimmed just 1 coralite what would happen, well now I've got a new branch growing from apart of the branch where there were no signs of new growth previously. I thought this was pretty cool & will try it on other corals to try & inspire new growth.
So I now wonder if there were 2 corals about to touch each other if you were to trim coralites off a lower section of the branch, if the branch would stop shy because it would be dedicating growth energy to the trimmed coralites instead of the end of the branch. Does anyone know anymore about this?
