You seem to be interpreting "please be careful when..." as "don't". I'm not sure how that interpretation makes any sense. Obviously they just mean, first kill the service (or better yet, shutdown the machine entirely) and then revoke the token...?

Here being careful about revocation means:

Make sure to have an up-to-date backup, that's offline, or at least not mounted on the affected computer.

Check for the dead-man switch, and if present, disarm it.

Only then revoke the tokens. Instead of immediately revoking the tokens, like one would normally do. Nobody is suggesting to keep the compromised tokens active longer than necessary.

my understanding is that careful means cleaning up the dead-man’s switch before revoking
