Don't feel stupid, I just barely mastered it myself after long hours ;-)
Attempt at explanation: SecureScreen is derived from
VelocitySecureScreen. The latter calls the isAuthorized method and if
and only if it receives the return value 'true' it calls the
doBuildTemplate method. So your method was never called in the first
place and the context variables could not get set.
Take care,
