Judy, I'm sure Joe will eventually cut it back. He just wants to make sure there's some to cut back to!
This photo of some of the branches shows some of the structural problems:

The longer branch has virtually no taper at all. It didn't have any foliage blouse to the trunk until he made the cutback, and now new buds have started. Once they grow out some, he'll be able to do a substantial cutback.
The shorter fork does have a branch he could cut back to. It looks like it's still thin enough to wire.
The thing is, to develop proper branches this thing has to be allowed to grow out substantially, then cut back. Repeatedly. To be able to get good growth requires a strong active root system. Which is unlikely to happen in a bonsai pot. My recommendation would be to transfer it next spring into a wooden grow box. Just so the roots will have room to grow to support good branch growth.
Whether he wants to adjust the trunk positioning is up to him.
