I would ignore anything Michael Dorn did, because I can't stand Worf. First he ate TNG, then he ate DS9.
Ignoring the whole canon bit for a moment... may I ask what you meant with the "he ate TNG, then he ate DS9" phrase? I'm not familiar with that one.
The closest connection I can think of is the Troi cellular peptide cake (with mint frosting).
Isn't Timewalker suggesting that Dorn subsumed the identity of those shows beneath himself? I certainly don't agree, but that seemed to be his intention.
