I personally heard him say this at an LCA mtg once

One pilot asked him...

How would that work for Reserve crews?

...or when the Capt & FO lines in the bid pack don't contain the same trips?

...or when guys trip trade last minute?

There was a long pause before he just moved on to a different topic

He clearly hadn't thought it thru

That's what happens when you don't fly the line regularly, and only bounce your ideas off others flying desks too
