The documentation says:

 The child process is created using vfork(2) instead of fork(2) when
       either of the following is true:

       *  the spawn-flags element of the attributes object pointed to by
          attrp contains the GNU-specific flag POSIX_SPAWN_USEVFORK; or

       *  file_actions is NULL and the spawn-flags element of the attributes
          object pointed to by attrp does not contain
          POSIX_SPAWN_SETSIGMASK, POSIX_SPAWN_SETSIGDEF,
          POSIX_SPAWN_SETSCHEDPARAM, POSIX_SPAWN_SETSCHEDULER,
          POSIX_SPAWN_SETPGROUP, or POSIX_SPAWN_RESETIDS.

So using the flag is necessary if you want to force the use of vfork when passing any of the flags specified in the second point.
