DY – The people who have told me this story have always used it to show that Rav Moshe “really held” that chalav stam is assur. The story refutes this because if that were true, it would have been impossible for him to drink it even by mistake because ??? ???”? ???? ???? ???.
That said, I think the real moral of the story (if it is true) is about the incredible sensitivity he had to something which he held should not be consumed by a baal nefesh, as per Joseph (Lior), et al.
IHLH – I’m not sure what you thought I meant. Chas V’Shalom, I did not intend anything other than the greatest respect for Rav Moshe. Let me be clear. My point was that since Rav Moshe is obviously included in “??????”, it is inconceivable that he would have consumed something that was not kosher according to his own opinion.
