That's because APS-C is not 1 stop from FF, but 1 and 1/3. There's only 2/3 stop difference between M4/3s and APS-C.

But I thought Canon's was 2/3rds of a stop difference while APS-c (such as Nikon uses) was 1 stop difference.

Here are the actual area ratios:

FF / 4/3rds = 3.8

FF / APSc = 2.3

APSc / 4/3rds = 1.6

or

4/3rds / FF = 0.26

APSc / FF = 0.43

4/3rds / APSc = 0.61

I concede the apertures were probably closer in the first chart than my amended chart.
