True, but you announcement insinuates the PMs for special roles were already sent out prior to the announcement (such as , "if you didn't get a PM from me, that means you're a regular townie). But you quickly announced Lycee as a player within a minute of that announcement. It would have been very difficult to re-randomize and re-send PMs.
Of course this is all speculation. You could have re-sent PMs a few mins later, but I find that highly unlikely because it's more likely SOMEONE would have slipped and mentioned it (having a role reversed or added) at some point.
