Correct, but no interpretation is needed.
At the moment the decision where to land has to be made, the scrambled fighters are in the seazone where they scrambled to.
So it is one move from there.
@rulebook:
After all combat is completed, each surviving scrambled air unit must return to the territory from which it was scrambled. If
the enemy has captured that territory, the unit can move 1 space to land in a friendly territory or on a friendly aircraft carrier.
If no such landing space is available, the unit is lost.
