In most shells, a subshell forks and in any case, subshell or not, the shell will fork a process to execute that ping command in a separate process as there's no shell that I know that has ping as a builtin command. But the point here is that the shell will wait for the termination of that process. & doesn't make a difference whether the shell forks or not (it forks with and without &) but whether the shell will wait or not for that process to finish before carrying on with the rest of the script.
