I apologize I wrote the above wrong the company can add additional flying per contractual guidelines but all flying must be within the FDP limits. At a previous carrier we had no such requirement to check our schedule so it was considered the end of the FDP.

The reg reads a little strange:

"If the certificate holder does not have an affirmative intent for no further aircraft movement at the conclusion of the flightcrew members last scheduled segment, then the flight crew members FDP has not ended."

So since we have the requirement to check our schedule after our last segment we fall under the above.

At the previous carrier we had no requirement to "check in" after a reserve pairing thus our FDP terminated at that time.

clear as mud?
