Right. The mats are usually grounded directly since they have a fairly high internal resistance, while the wrist strap that features a metal contact to the user has a 1 meg resistor in series.

Also, I believe ESD wrist straps should have something like a 1 meg ohm resistor in the ground connection to mitigate direct (and potentially fatal) shock to ground while allowing the bleed off static charge. A direct connection to ground is hazardous!
