I think you're wrong there. I believe the Moscow Patriarchate has said they do, and I think the EP has probably said something very similar.
Actually Moscow specifically said that by receiving heterodox converts through a means other than baptism no inference should be made that the Russian Church accepts the presence of grace in the heterodox baptism. Both Moscow and the EP officially have a "We don't know" attitude. As for which way do they lean unofficially... I think the EP probably does lean towards accepting RC sacraments. I also think the MP leans in the other direction if only a little bit. It should be noted that in the near future the bishops of ROCOR will be sitting in the Holy Synod of the Russian Orthodox Church. They are NOT friendly to anything Roman.
On a brighter note the very fact that such an extremely bitter schism has been ended gives me hope for all kinds of miracles. :-)
