Being *too* conductive is not ESD safe. The idea is to let the charge
drain away slowly. If a charge drains too quickly, it can induce a
charge nearby that might not be protected, like something internal to
a component.
Exactly, the same sort of problem you can run into with the black
conductive bags (such as the black conductive bags IBM used to pack their
boards and drives in).
