I don't mean to split hairs here...but I guess I kind of do. I'll apply what seems to be ypical ROAC/GOC logic to this question again. St. Silouan was in communion with "heretics" according to the ROAC/GOC view. One of these heretical bodies was the "Moscow Patriarchate" started by Stalin(in your view)...the "Soviet Church" we hear so much about here which was partly responsible for the persecution of the True Orthodox Church. If St. Silouan was in communion with these "heretics", than he himself must have been outside the Church, by your usual logic. How can one in communion with heresy be given the gifts of the holy spirit and the grace required to become a saint?
What hath light to do with darkness.. (blah blah blah)
(Again, I don't believe this at all... it's just that his saintliness does not fit into ROAC "true orthodox" logic)
Maybe you have heard Gregory of Denverand do not to ROAC (he was deposed by similar thoughts to those that you have mentioned). And for your logic I see that then ROCOR was also in communion with the MP every year through its communion with JP and SP. It is ridiculous. The same logical ROAC is that of ROCOR, because we inherit St Silouan through them. This ROCOR that I mention here is not the one of now but the one of before. I don't know to where you want to arrive you with this discussion.
