That's not true. It *might* be a good idea to assume it, but given the
intention is perfectly clear, it's certainly not a requirement.

It would be better if the intention were explicitly written out (ie,
"You may distribute and modify provided you do such and such") rather
than implied ("You must do such and such if you redistribute"), of course.
