That’s certainly the way I read it.

The SAVE command most probably is a locally written command or DCL procedure invoked by a symbol that does the magic of copying the files to the floppy.

The OpenVMS EXCHANGE command is the most likely tool used to transfer the data. As it’s name implies, it is designed to move data to and from foreign systems (where foreign in this context is most often a PDP-11 :-))
