That would depend on if you were riding on the shoulder or taking a full lane. If you are taking a full lane, on a two lane two way road, then no passing.
Yes, if I'm taking the full lane. It's quite clear from the OP that he was not doing so--he was on the right side of the middle lane intending to take a left turn, positioning that made no sense if signaling intentions.. It's why I'm always going to take the lane to avoid a right hook at an intersection where a right turn is possible or if I'm taking a left turn. Even in NH, those are FRAP exceptions.
If you watch urban intersections, cyclists pass each other all the time. I think it's absurd to pretend this is some sort of general taboo, and if you do that IRL, don't expect anyone else to be on the same page.
