I don't recommend pruning past a terminal bud. Very often no terminal bud means a dead branch.
Not sure what your reference to bonsai soil was for. I use 100% calcined clay. BUT for this job I just scrapped off the top 1" of nursery soil and added some Miracle grow, I did this so that as I water the nutrients of the fresh soil can wash down into the older soil.
YOU don't recommend it, but from what I have read it has a lot to do were you live. In Central Florida I see a lot of Bonsai people doing trunk chops like this, I don't see any reason why deciduous trees that back bud really well would need a terminal bud. We had some bushes that grew out of control around our screen enclosure area. We did some serious trunk chopping and every single trunk has new growth sprouting all around the trunk. Why would this differ in any way?
Don't take my post as being defensive I'm just trying to make sense of what I've read, and now what you are telling me.
