The two stats are essentially reciprocals of each other. The assumption is that each team should somehow get an equal dose of the two in combination.
It is basically saying that your position on two different distribution charts should average out. If your goaltending is better than average, then your shooting percentage should be below average in order to compensate.
Pretty ridiculous when you break it down.
However, laws of large numbers. Because the league aggregate adds up to 100, and because there are so many players and variables involved for each team, the actual results don't vary a great deal from the mean -
they are so muddied, that every team looks brown.
As a result, data minors looking for something to talk about, have a perfect opportunity here: greater than 100 - lucky. Less than 100 - unlucky.
Four legs good...
