Exactly, why make things complicated when you can leave it up to the UA as it has to deal with this anyway. A B2BUA can very well behave as if it where almost a proxy.

Even if the AS wants to act as a B2BUA, the AS can still establish
multiple dialogs back to A, so the issue of sorting this out is left to
A.
