Sorry, I misread your example, agreed it can't be neither. I still don't see that as a shorthand it's very useful. A good team will tend to be above 100 a bad team will tend to be below, but neither says why. True extreme values can indicate a non-sustainable situation but there should be no expectation that numbers revert to mean. A team with a great goalie has an automatic bump on PDO.
Even worse IMO is individual PDO. Player X has a PDO of 99 - what does that mean? They don't control save percentage and it's not even a good indicator of defensive performance, which is anyway masked by adding in smaller sample shot %. Garbage stat.
