Yeh, thats the release its based on, not the release it was first merged
into, usually the subsystem branch for the next release is based on one
of the rc's of the previous release.
I have this slow hack in my ~/.gitconfig:
[alias]
tc = tag --contains
vc = "!vc() { for i in `git tc \"$@\" | grep '^v'`; do echo \"$(git log -1 --pretty='%ct' $i) $i\"; done | sort -n | head -n1 | sed 's/^[0-9]* //g'; }; vc"
Then:
$ git vc 515a6393dbac4f4492237c7b305bbf9c4c558a1c
v4.0-rc1
You can do something sort of similar with git describe --contains:
$ git describe --contains 515a6393dbac4f4492237c7b305bbf9c4c558a1c
v4.0-rc1~4^2~26^2~34
But if you have other tags in your tree between the commit and an
upstream release it'll sometimes show that instead which isn't very
helpful.

No idea, just a random observation.
Documentation/process/stable-kernel-rules.rst uses <>, but also has a
weird version comment format more like below which I'm not too keen on:
Cc: <stable@xxxxxxxxxxxxxxx> # 4.0.y-
