You are desribing a slight cut placed directly after a young bud, just deep enough so that the nutrients will go into the immature bud instead of going into the top of hte plant. A sort of diversion of nutrients. But the bud must exist before this can work out. You cannot utilize this technique on a branch where there are no leave or buds. It's quite tricky.

I have to say though, that if you trimmed off hte top of your beautiful candelabra, a side branch can easily be trained as the leader and in not time it will not be discernable that you've nipped off the top. I can see from your photos that you did this correctly. When your plant reaches the height you want, you can again nip off the tips, which will encourage the branches to thicken (and leaf out).

Hope that helps.
