Airport reserve can occur with no flight segments assigned. However, once flying is assigned, the FDP ends once the last flight segment is completed (unless more flight segments have been assigned prior to brake set on the last assigned flight segment). That's why the definition in the reg explicitly states airport rsv is only part of the FDP before or between flight segments (if any flight segments are actually assigned).

(FDP) means a
period that begins when a flightcrew
member is required to report for duty
with the intention of conducting a
flight, a series of flights, or positioning
or ferrying flights, and ends when the
aircraft is parked after the last flight and
there is no intention for further aircraft
movement by the same flightcrew
member. A flight duty period includes
the duties performed by the flightcrew
member on behalf of the certificate
holder that occur before a flight segment
or between flight segments without a
required intervening rest period.
Examples of tasks that are part of the
flight duty period include deadhead
transportation, training conducted in an
aircraft or flight simulator, and airport/
standby reserve, if the above tasks occur
before a flight segment or between flight
segments without an intervening
required rest period:

I don't think I see the word after in the reg
