I still have one huge suspicion: that next color is guessed by the decoder only at the first subcarrier peak.
In a simplistic sense, it's impossible to detect the amplitude and phase of a QAM signal until a substantial portion of a whole period has arrived.

I think broadcast TV moved the chroma signal earlier relative to the luma signal, so that both would appear on screen in the same horizontal position without needing yet another analog delay line in the end-user's set, but direct generation as with the NES doesn't have that.
