Yeah, I guess I don't understand either.  ... the piece I installed did transition to rectangular before the entrance. 

That is one way to do the transition. Just what I meant. You just said it was 6" round duct before.
The other way would be a round to square "adaptor" in the piping just as it comes to the can.

If you transition to rectangular before the entrance it will make the hole a LOT easier to cut with a good fit.
