================================
Response from the Working Group
================================
They should be consistent but do not HAVE to be identical.

In this case we would recommend that you make them identical so it was
clear to the user that if they had visited one, that clicking on the second
link with the exact same text would take them to the place they had already
been.   If they are slightly different, it might imply that what is at the
other end is also slightly different.

We are adding the following example to Understanding SC 3.2.4 to clarify:

Example 5.5: Icon and adjacent link to same destination
An icon with alt text and a link are next to each other and go to the same
location. The best practice would be to group them into one link as per H2.
However if they are visually positioned one above the other but separated
in the source, this may not be possible. To meet the Success Criterion, the
link text for these two links need only be consistent, not identical. But
best practice is to have identical text so that when users encounter the
second one, it is clear that it goes to the same place as the first.
