Two reasons:
- It's consistent with the `else` branch in the `for` loop of
`LocaleMatcher.{filterBasic,filterExtended}` (main)
- I thought that `caseInsensitiveMatch` being first made it clear the need
for `lowerCaseTag` but now noticed that the comment was meant for
`{shouldIgnoreFilterBasicMatch,shouldIgnoreFilterExtendedMatch}` instead

I've tried to follow your suggestion but I think this comment is no longer
necessary. (The tags are no longer removed and no collections are updated.)
I had noticed that this comment could not be added back verbatim to the
modified code. Hence, I tried to rewrite it. However, I noticed that the
comments for
`LocaleMatcher{shouldIgnoreFilterBasicMatch,shouldIgnoreFilterExtendedMatch}`
clearly covers what we wanted to highlight here.
Let me know if you disagree together with a comment that you'd like me to
include verbatim.

Done.

Done.
