I don't think it does. Section 4.4 says it contains one path even if there are multiple RCPT commands, 7.2 says sort of indirectly not to put blind recipient addresses into the received header, 7.6 reiterates the blind recipient stuff. On the other hand I think it is clear from context that the FOR clause is supposed to contain a RCPT TO argument, with considerable ambigiuity which one to use if there were several recipients, and whether to include it at all. The stuff in 7.2 and 7.6 seems to be saying to look at the message header and only include the FOR if it matches one of the header recipients, but ugh.
