The term "version URL" simply means a URL that identifies a version.  In
your example I'm not sure what you mean by "relative URL".

Servers may support deleting individual versions (as well as the entire
versioned resource).  It would be undesirable for servers to reuse version
URLs since they represent a 'stable' reference to a particular state of the
resource, and may be used as such by other persistent resources.  Clearly
if the server reuses a URL that would be a bad thing in such circumstances.

Can somebody clarify what this would mean:

Whether or not I agree with this, I find the phrase "version URL" to be
ambiguous enough that I'm not certain what this comment is supposed to
so I'll start with an example:
 - foo.doc is created
 - foo.doc is made versioned and "foo.doc.__v1__" is defined as the
version URL
 - All of foo.doc is deleted
 - foo.doc is created
 - foo.doc is made versioned, NOW, according to this suggestion, the
version CANNOT be called foo.doc.__v1__ therefore is called foo.doc.__v2__

Is that the intent?  if so, I'd have to disagree with this; although it
might be desirable for a server to avoid ever having a version URL re-used,
it ought not to be part of the standard.  I don't actually think it's
relative to the standard, although it may be very relative to good server
