Return in Paranthesis Does Not Return from Function

hi() {
  # Return wont work as expected since it will exit out of parenthesis 
  # and not the hi function. Allowing this method to continue further.
  echo "blah" | grep o1 || (echo "nope"; return 1)
 
  echo "FINISHED in HI"
}
 
hi

WHY: because its () is a subprocess. See parenthesis-spawn-a-subshell
