I think the original idea by Gulenko is that you either belong to one subtype or you belong to the other subtype.
There is no half way.

I think being balanced between two subtypes is something created by Ganin, not Gulenko, because:
1) I have only seen Ganin talk about the possibility of being balanced between 2 subtypes
2) If Gulenko intended there to be a balance between 2 subtypes, he would have created 3 descriptions for each type.

What do you think?
