The stand right, walk left tradition here usually works well, and it's not like the left is empty for a lack of walkers.
Maybe it's cultural or depends on how eager to walk people are as to utilization factors.

Doesn't this depend on the walking/standing density ratio and walking speed/escalator speed ratio?
Let say the walking density is 1/2 of the standing density. If the walkers walk at the speed of the escalator (i.e. their speed relative to the ground is 2x the speed of the escalator), then the throughput is the same.
Optimal Tip-to-Tip Efficiency is well studied mathematically. Here's the authoritative paper: https://www.scribd.com/doc/228831637/Optimal-Tip-to-Tip-Effi...
There are other issues than eagerness to walk, like physical disabilities and collision avoidance. Ultimately two-speed traffic only works better if you're far from congestion, I believe.
