question about heritage auctions

This is a dummy question but give me some slack
In the heritage archives section of past prices realized,is the price it sold for not include the Buyers premuim. Example; Say the sold for price is $1000 and beside it it says includes BP. Does that mean it is added on to the $1000???

they only show the realized price with BP included if you're looking at the listing of recent prices realized on a current auction.
