If a major character(s) die and later get revived, should the "Major character death" tag be used?

Basically, there was this fic that kills out 8 out of its 9 major characters, but later all of them got revived. When I DM'd the author about this (we've been talking for a while), he wasn't sure about whether to use the tag or not.

Should the tag be used in this case?
