What does that mean?

It is feebly attempting to say that, because these are control flow
functions, the argument is really a thunk that the function has
control of when and how it's executed, much like in the constructs:

   $x && thunk
   $x || thunk
   $x ?? thunk !! thunk

Haskell demonstrates that this is simply lazy application.
