Will reloading supervisord cause the process under its to stop?

I try to figure out when I used reload command to supervisord. Will it stop the processing currently executing under it? I used below steps:

mlzboy@mlzboy-mac:~/my/ide/test$ pstree -p|grep super
        |-supervisord(6763)
mlzboy@mlzboy-mac:~/my/ide/test$ supervisorctl 
daemon                           STARTING   
supervisor> reload
Really restart the remote supervisord process y/N? y
Restarted supervisord
supervisor> exit
mlzboy@mlzboy-mac:~/my/ide/test$ pstree -p|grep super
        |-supervisord(6763)

I found that the process id is not changed. So does it prove reload will not stop the processing under supervisor control?
