Since the spec relies on the Talking Book spec, I don't see how we can ignore it.
Section 2.4.2 of the epub 2.0.1 OPF spec spells out all the exceptions to the Talking Book spec definition of the NCX. And there's nothing in that list of exceptions that says two navPoints cannot point to the same target in an epub's NCX.

2.4.2 says that the NCX spec's references to links to SMIL locations should be read as referring to links to XML elements instead.
