Nope, you're right.  wpa_supplicant.conf(5) calls it out clearly:

     scan_ssid
             SSID scan technique; 0 (default) or 1.  Technique 0 scans 
for the
             SSID using a broadcast Probe Request frame while 1 uses a
             directed Probe Request frame.  Access points that cloak them-
             selves by not broadcasting their SSID require technique 1, but
             beware that this scheme can cause scanning to take longer 
to com-
             plete.

though obviously you need to know to look there.  Thank you.
