Wrong answer, Dirk Vdm. (And I seriously doubt that anyone else
will concur with you.)

Dude, as usual with this kind of stuff, he is fully correct.
You should thank Dirk for patiently explaining to you the ABC of velocity
measurement.

At that point in his book, Einstein had yet to even mention the
relativistic velocity composition theorem, let alone derive it.

Exactly, Einstein *used* "c - v" for deriving that.
