Indeed!
I always stay out of the firing line when spinning the grinder up to running speed with any of the non-electroplated wheels.
if you are using a sharpening jigs you don't have to stand directly in front of the grinding wheel to get the results you want.
But, when I'm freehand sharpening I tend to eyeball down over the tool/wheel and as a result dance about through the firing line. So it's some comfort to know that the electroplated CBN wheel isn't going to have a go at me...:)
