It has to run rich long enough to thin the oil with unburned gas. If the oil is thin enough, it will get past the oil control rings on the pistons and the seals on the valves and be burned. If this happens, the oil burning is the least of your problems. Oil this diluted does a bad job of lubricating and it's just a matter of time before the engine is destroyed.

Engines running 'rich" do not cause the engine to burn oil.
Rich refers to the fuel air ratio, to much fuel not enough air.
The car will have grey / dark smoke from the exhaust when it is very 'rich', that is not oil burning, it is soot , unburned fuel.
White smoke is oil.
burning oil is not caused by running fuel rich.

It's not burning oil. The black smoke you see is unburnt excess fuel.
