Does a HS Camping Pass Really Need a 4 Day Pass?

I bought my camping pass 2 days ago (6/1) from the ticket/swap section. I am hoping I dont need the 4 Day Pass to be able to use it and that the requirement for the 4 Day Pass was in place when the camping passes originally went on sale? :huh

It needs a four day pass or a day pass to each of the four days of festival.

You need to have either a 4 day pass or all 4 individual day passes to camp at the high school.
