Working Group Resolution (LC-2868):
Thank you for your comment. It seems that there may be a misunderstanding
of the 2.4.4 understanding text.  There is no requirement implied that the
links _must_ have the same descriptions, just that they should.

Your point about 3.2.4 only applying to links in sets of pages is correct,
so we propose modifying the sentence in 2.4.4 to:

It is a best practice for links with the same destination to have
consistent descriptions (and this is a requirement per Success Criterion
3.2.4 for pages in a set). It is also a best practice for links with
different purposes and destinations to have different descriptions.
