You are correct.

The Lisa Office System's Desktop Manager ("finder") copying methodology was to always _MOVE_ a document whenever you copied it. To make a copy (duplicate) you used the Duplicate command (it may have been called Make Duplicate but that sounds too wordy to me).

This made "copying" very consistent in the Lisa user interface, but was a bit confusing to users. They could end up "copying" a document from a floppy to the hard disk and then ejecting the floppy without realizing the document was no longer on the floppy.

The Macintosh Finder only moved documented when copied on the same disk. Copying between difference disks did a copy.

The Lisa's copying methodology was most likely based on the Lisa's limited disk space resources. Given that the Lisa supported virtual memory for applications and their data files, disk space was precious and keeping multiple copies around may have been a resource hog.

There is a discussion of this either in the Xerox retrospective conference proceedings from around the late 1990s or in the Inventing the Lisa user interface article.
