No. Because the department that has advance warning of internal tests will be unlikely to be the first targeted by real phishing emails.

This doesn't seem like much of a reason to try and dissuade employees from discussing these things though.

I think there are probably a great many sysadmins, security analysts, and ciso's who can only dream of a day when run-of-the-mill employees are having casual conversations about phishing and identity security at the office.
