the kill command doesn't force a running john session to report
it's current status.
It just forces the process to update john.pot as well as the
corresponding .rec and .log files - which normally would
be updated every 10 minutes (unless specified otherwise
using the Save = option in john.conf).

john --show and john uses john.pot to report which passwords
have been cracked.
john --status uses the information in the .rec file to report
the status.

So the kill -s 1 (under Unix/POSIX) is a method to make sure
john --status will  show information which is up to date and not
up to 10 minutes old.
