A number of these Captains are Line Check Airmen.
Line Check Airmen usually bid as Captains. With this new contract, the Company can withhold the lines awarded to these Captains from the First Officers bidding on the lines that these Check Airman have been awarded, for the purposes of Checking activities. That way, they don't have to remove a F/O from the trip to conduct these training activities and pay them to sit at home.
However, a number of these Captains are pilots that were not displaced back to F/O's. Why? Because they will be needed in the near future and it would not have been cost effective to have downgraded them, just to turn around and have to upgrade them again for the summer flying.
Thus, this explains the disparity in the number of Captain lines and F/O lines.
