BB Passport -When I set a snooze interval, will the reminder be on the day of the meeting?

I have a calendar entry for a meeting and I set the meeting reminder for 2 days before.
The Snooze Interval setting is for 15 minutes before.
When I get the reminder 2 days before the event and I select SNOOZE. When will I get the next reminder? 15 Minutes later "2 days before" the event OR 15 minutes before the event 2 days LATER---which would be the day of the event?
My understanding is that the reminder would be "2 days before" the event.
Please advise Thank you...
