What significance does that particular interpretation have for any JW or any other person of another denomination?
I can't think of any, but maybe you can.
Pointing out a detail like this to an Active™ JW will likely get you branded as a nit-picker, and someone who just wants to be negative for the sake of being negative.
I agree with you, in principle, that the translation of the NWT is highly questionable and completely unreliable, but given that it's on something that is of such negligible importance, I sincerely hope that you find bigger fish to fry than this.
