He's probably running the grinder on the tailstock ways

I might have to take that back... PT later on down mentioned that the L&S
carriage runs on both front and back ways.

He's not running on the functional surfaces of the ways at all:

Even though he claims those surfaces are ground in the same setup as
the working surfaces, I'd be concerned how much care was taken
grinding the non-functional surfaces. And the rollers have the
disadvantage of transferring small irregularities to the grinding
wheel. I guess the cost-benefit calculation has to include how bad the
worn really ways are, and what you're hoping for after the regrind.
