If SSH authentication does be performed via PAM (so called keyboard-interactive 
authentication), you do have that behaviour. But, IIRC, you perform 
authentication with SSH public key, which completely bypasses PAM infrastructure 
at the authentication stage regardless of 'UsePAM yes' setting, thus the result 
you observe. PAM has nothing to do with that. Please carefully read sshd_config 
manual.
