No it means you can't use wrist detection to auto-lock because the metallic pigments in some tattoos interferes with passive skin sensing. There's an option to turn it off.

How many people have metallic pigment tattoos on their wrists?

AFAIK, very few, because optical pulse oximeters usually go on fingertips or earlobes, even ones that are attached to wrist-mounted displays.

thats dishonest/apple fanboyism. The watch doesnt work as advertised.

Edit: on people with dark tattoos.
