Redfin removing prior listing prices?

I've had my eye on this house in Normandy Park for a few months, currently listed at $529K.

But I noticed some interesting things - first the seller has either some optimism about the RE market in raising their asking price for a stale listing, and second, Redfin doesn't have the prior pricing, which was $499K for 5 months or so.

I've always seen the prior listing prices or price changes, but they were always price drops rather than asking price increases. When the asking price is increased, does Redfin have some MLS obligation to delete the lower previous asking prices?

czarmar,
Redfin will give the price history for a house with a particular MLS number, but if a property sees significant remodeling, or a price change of five percent or more ( higher or lower), the seller can cancel the lsiting and relist with a new MLS number, and Poof! the price history is gone!, because the new MLS number doesn't have a history.
I can't comment on this particular house, because as a real estate broker I'm not allowed to, so I'm only speaking in general terms, of course.
