More accurately, they're right in the context from which the speaker

Only within Python's terminology. This, of course, conflicts with the
meanings that adhere to those words just about everywhere else on the
user's operating system.

More accurately, the meanings you list in the hypothetical responses
above are entrenched and more useful for general use.

In principle this would be good. However:

How then to distinguish between these? They're clearly separate
concepts, and I think they need distinct terms.

That one would be good.
You then have the converse problem of changing the use of terminology
that is currently entrenched in existing Python documentation and
