The first part of the "or" is not true: you can pass the result of $(pwd) to a command, and it means the same as $PWD; I would even recommend against $PWD so that a reader does not have to wonder "why pass $PWD, but check for $(pwd)?"

The second part I don't know whether it is true: I haven't noticed a pattern where people did it the wrong way, therefore, I'don't even know whether $PWD is really *always* required. Do *you* know?
