My updated insight is as follows- the averaging simply allows for an easier way to compare teams that have different number of matches played. For example:
Team A has a QA of 100pts/match and 4 games played
Team B has a QA of 110pts/match and 3 games played

This is a lot easier to compare than
Team A has 400 points total, and 4 games played
Team B has 330 points total, and 3 games played
