merging repos with svnadmin load, "rev numbers will be off"?

I have clarification question for a FAQ

-------------
http://subversion.tigris.org/faq.html#multi-merge

"How do I merge two completely separate repositories?

If you don't care about retaining all the history of one of the
repositories, you can just create a new directory under one project's
repository, then import the other.

If you care about retaining the history of both, then you can use
'svnadmin dump' to dump one repository, and 'svnadmin load' to load it
into the other repository. The revision numbers will be off, but you'll
still have the history."

What does that last comment mean, precisely? I'm hoping it means:

"If you refer to specific revisions in comments, bug trackers, etc, then
your revision references will be inaccurate after the merge. The revision
numbers will be positively offset by a constant, specifically the revision
number at the time of svnadmin load. For all subversion operations, such
as identifying branch points, merge ranges, etc., the validity of the
imported changesets, and its copy and revision functionality in subversion
will be unchanged, except for this revision number offset."

Is that anywhere near accurate? I have several small per-project
repositories that I'm considering whether to merge or import losing
history. Thanks.
