If you have a VIP Pass you have to renew it every year. No matter when you buy it, It always expires June 30th unless it was advertised to continue through to the following year. Eg When they start selling them in May/June to continue through this year to the following June 30th. With the Memberships they automatically renew if you don't cancel them so they are ongoing and don't have an expiry date.
If you actually receive an email to renew your VIP Pass and you follow the link and are actually purchasing what is called a Renewal then you continue to use the same pass. We get a lot of people that think they are buying renewals and show up with their old passes to find that they actually just repurchased the same pass so the ones they have are expired. They then need to get a new one printed.
