The 0.01 m value is hard coded (https://github.com/NREL/EnergyPlus/blob/develop/src/EnergyPlus/SurfaceGeometry.cc#L6414). Seems like the engineering reference is out of date.

The 0.01 m value is hard coded for collinear points (https://github.com/NREL/EnergyPlus/blob/develop/src/EnergyPlus/SurfaceGeometry.cc#L6414). Seems like There is a difference between the engineering minimum precision (1 mm) with which geometry is modeled and the minimum distance between two vertices. The idea is that the resolution of geometry modeling calculations should be a bit finer than the resolution you can enter for geometry on input. The Engineering reference could be clearer but it is out of date. talking about resolution and doesn't actually say what the collinear check is, that is in the warning message.
