Did you get one free HHN ticket with your premier pass? If so you only get that one free ticket as that promotion is a 1 time free ticket for 1 premier pass. Starting your premier pass dates to include two years of the HHN time period does not mean they would give you two years worth of tickets.
A regular 12 month pass starting in October would definitely fall in the HHN timeframe the following year but they do not get an additional ticket.
