I think the concern was explosion of fine dust and sparks from grinding.
Filter, filter.
And further away is best - in the same room - e.g. turn around and take
a few steps - keeps the legs functional - not in a position to long.
It also gets the eyes to focus better - to long at the same distance is
bad as well.

I have a 14X22 basement area: double bag dust collector behind the
lathe, two circulating filters (one commercial and one homemade).
Still get some dust accumulation and always wear respiratory protection
while power sanding. Having your sharpening equipment very far from
the lathe wuld be a pain in the neck.
