It's where the seller provides the necessary paperwork so you the buyer don't have to withhold proceeds of the sale to remit to Hawaii's gov't. It's normal part of the process for seller's that aren't resident of Hawaii if they so desire to go thru those steps. Most sellers don't, and just lose a portion of the sales proceeds to be paid as taxes on the sale, which they can claim back when establishing proper cost basis when filing Hawaii income taxes, which often doesn't happen.
