When someone accepts a revision, I get an email that says `[Changed Subscribers]`. While this isn't false per se, it's far more relevant that the revision was accepted, but I have to read through the body of the email to get that information.
I think what's going on here is that the designated reviewer is a project, and when someone from the project does the review, they (the individual) gets automatically added to the revision, and some other stuff happens. I get an email with all of these things, but "changed subscribers" happens to be first. Here's an example email:
Subject: [Differential] [Changed Subscribers] D40: Create cgi.cfg after installing icinga-cgi
jbowman added a subscriber: jbowman.
jbowman accepted this revision.
jbowman added a reviewer: jbowman.
jbowman added a comment.
This revision is now accepted and ready to land.
Looks good, tests good.

Similarly, news feeds (in this case, for the user `jbowman`) say "changed subscribers" rather than the more relevant "accepted":
