Yes, and no.
Standard Pat-Down
is for opt-out of the WBI, it's also for resolving alarms from the WTMD that can't be resolved by divesting more metal, it's also for, like, when a person has a pace-maker implanted.
Targeted Standard Pat-Down is far more specific. Like... say you come through with a baggy sweater on. The TSO would perform a pat-down of the upper body everywhere the sweater is loose on you - it's targeted. Same for baggy pants, only in that case it would be your legs that receive the pat-down and not the upper body. As I understand what Bob's said on the Blog, it's also for clearing anomalies from the WBI device. Like, say, there's an anomaly on your arm - your arm will be patted down. It's a "targeted search."
(Previously, this was called a "bulk-item pat-down," and still is by many TSOs.)
The Resolution Pat-Down is something else entirely, used, in my observations for ETD alarms on the passenger
(such as from the ETD of a TSO's hands following a Standard Pat-Down). It is, literally, an alarm "resolution" procedure.
