Close - they allow for a change in start point by 500 miles, but there is nothing (that I've seen) which has the rule written down specifically.
Most agents will allow a change of connecting flights, if the departure time is changed by 2 hours, but it is rare that they will immediately advise that the start-point can be changed.
