Well, at the risk of nit-picking, belabouring a point, and flogging a life-challenged horse, you did use the word 'explicit', which would suggest to me that it was your opinion that the interpretation in question was the one intended by the anonymous author.

By the way, when I say "rather subtle", I don't mean TOO subtle. On the contrary, I find what I take to be the subtlety of that interpretation appealing. I'm just surprised that someone else would find it "explicit" and "obvious", since it had never occurred to ME before ...
