I agree with the general idea - but I'm not sure that there's meant to be any direct connection here (no pun intended) to Bobby in the lyric. I don't think the song is about HIM in any direct way - it's Marta's impressions of the crazy/busy life in Manhattan for sure, but it seems to me that the subject of this section of the song is the more general "they" she keeps mentioning ("they meet at parties" etc) rather than Bobby specifically. Bobby can and would certainly be one member of the "they," of course - but it's not just about him.
