I think that the reason is given in the paragraph above:

While the features of VoiceXML 2.1 are orthogonal additions to [VXML2],
a VoiceXML application should not mix documents of both types. The
handling of a single application that mixes VoiceXML 2.0 and VoiceXML
2.1 functionality is platform-specific. Reasonable behavior in this case
ranges the gamut from successful execution to the throwing of an error.

IMHO the idea is that there should be a clear statement of the authors
if they write for 2.1 or 2.0.
