Quoting Documentation/process/submitting-patches.rst:
"
Both Tested-by and Reviewed-by tags, once received on mailing list from tester
or reviewer, should be added by author to the applicable patches when sending
next versions.  However if the patch has changed substantially in following
version, these tags might not be applicable anymore and thus should be removed.
Usually removal of someone's Tested-by or Reviewed-by tags should be mentioned
in the patch changelog (after the '---' separator).
"

I guess that in this case you are right, it the change is not likely
"substantial".

Thanks!
