i mean, by the grammatical rules, it's still a valid reply to the comment.
[modifier][noun][verb][modifier][noun].
gödel reminds us: "syntax all on its own cannot determine semantics".
the point is to evidence grammaticalness despite apparent meaningfulness, and the commenter may just be seeking to simulate the point with a logically consistent application of the rules at play. "incomplete" with respect to [mimicking] or [reproducing] an [socio-historical cultural] artifact, but not inconclusive in evidencing the point (remixing to produce variations on the theme; i.e., there are evidences of +20-word recursive sentences, if not larger).
nothing about the buffalo sentence entails the social rule "when someone else posts the buffalo sentence, it must match the aforementioned sentence verbatim". permutations on the point are totally fair game.
