The entire "documentation" of this approach in Section 7.1 of TUS is:

"Some widely used implementations prefer storing the vowel letter and
the tone mark separately."

As long as implementations can deal with text that is not strictly NFC,
this seems like a sensible way to support multiple diacritical marks
while remaining compatible with existing dead-key implementations (Mats
stated that compatibility with the existing French layout was a
requirement) and existing architectural constraints.
