I don't think that's true -- a "full" rewrite is used in contrast to a "partial" rewrite, where only part of the system is replaced. It's called a "full" rewrite because the goal from the start is to fully replace the system with new code. Consider that if this were not true, then there would be no way to describe an incremental full rewrite, nor any way to describe a from-scratch replacement of a subsystem.
