Am I understanding about upgrading to an annual pass correctly?

I received a response from Disneyland today. They confirmed what was stated about the start date of the AP, it begins on the first use of the PH.

You don't necessarily pay the difference from what you PAID and the cost of the AP. This might be an extreme case (it happened with me), but if you got your ticket at a discounted price (I got a group discount through a corporate thing), then you pay the difference between the VALUE of the ticket and the cost of the AP.

What I mean is, I got a 5-day parkhopper (valued at $204) for $184. I upgraded to a Deluxe pass and I did NOT pay the difference between what I paid and the cost of the AP - I paid the difference between $289 and $204 ($85 paid).

Wow, I do think this is an extreme case but it would sure be nice if it happens to me. I got my 5-day convention tickets for $169 and it sure would be nice to pay $85 to upgrade rather than $120! But I am not expecting that.
