Fair enough. If the purpose of the case is to call the rules -as written- into question, then perhaps the observation is not valid in that sense.
It certainly is valid in the sense of how I see people submit observations in practice. The observation would be accepted as RG without question by anybody not actively evaluating the rules.
I stand by my statement that there is no objective need to single out this observation for any purpose other than your own. Cases that could be considered edge, like this one, are certainly a much smaller problem that confirmation bias and the rampant uncritical acceptance of the AI. Those are not the topic of this thread, of course.
