North End to Copley in 74 minutes

I like the MBTA trip planner a lot, but today it suggested something a little out of the ordinary. I wanted to know how long to allow for going from the North End to Copley, so I plugged in my coordinates...

The first option was what I expected, 20 mins on the green line. The alternative was 74 minutes via commuter rail, Porter Square, the red line and the #9 bus. Is that really the next best alternative? I would have thought the orange line from Haymarket to Back Bay station would be a decent second.
