Horizon Terminate command not working properly

when i run supervisor command to Start a new supervisor and after i run terminate command to suspend horizon, then horizon kills all other process but not process added whit command supervisor.

This is the process before i run horizon:supervisor command

ps afux | grep horizon vagrant 1520 0.0 0.0 14428 960 pts/1 S+ 08:36 0:00 _ grep --color=auto horizon vagrant 1484 3.7 2.4 367048 49588 ?

This is the command thaht i run:

php7.2 artisan horizon:supervisor cloudscan-aETE:supervisor-2 redis --balance=auto --max-processes=2 --queue=user-2 --tries=1 &

This is the process status after command:
