The point is that the terms re-dispatch and re-release are often miss interpreted The re-released destination is on the ICAO flight plan not the re-dispatched destination which is a company term. The ICAO flight plan sees it as a re-release point.

RIF (Re-clearance In Flight per ICAO DOC 8400/4) Routing from the re-dispatch point to the released destination. Is what is noted on the ICAO flight plan

On a re-dispatch flight, the flight is filed from the origin to the desired destination but “released” to a closer, intermediate destination. The fuel plan meets all the FAR 121.645 fuel requirements to the filed destination with the exception of the 10% reserve fuel. The 10% reserve fuel for the flight is modified to require only reserve fuel in the amount of 10% of the time from a “re-dispatch point” to the filed destination, rather than the full 10% of the time from the origin to the filed destination. This “re-dispatch point” is a point chosen by Flight Control along the route, common to both flight plans and relatively close to the end of the flight.

That should explain what your required arrival fuel is!

In no way am I saying that you violate a filed clearance, but clearly if you have the required fuel on board to reach your destination, you have the right to exercise your captain's authority to continue your flight to your re-dispatched destination or your cleared destination. It is the job of both captain and the dispatcher to ensure that a re-release is obtained in order to continue the flight. Thus the reason for obtaining your clearance 2 hours prior to your re-dispatch point. If in the span of two hours you can not contact a dispatcher something is a little amiss!
