Seems likely explanation.
How much additional fuel would they have been able to dump if they deliberately continued dumping after going below the min allowed dump height?
I am guessing that it would not be enough to make all that much difference.
At least they (apparently) terminated the jettison before landing, that could have been interesting.
The hazard of an overweight landing is a lot less than a high speed rejected takeoff and as others have pointed out would require an inspection with worst case possibility of a some repairs.
