Since when does eBay automatically up your bid to the reserve if you bid higher than said reserve?

It's been a while since I've bid on an auction with a reserve, so forgive me if this is the way it's always been.

- edit

I was the first bidder. So let's say the opening bid was $5 w/ a reserve and I bid $50 and the reserve was $30 so my bid becomes $30 automatically? Just incase my question wasn't clear.
