I would put zero credence in the distinction. There were multiple times we asked our realtor to check on a house and we were told it was in escrow or in one case sold, yet still sitting active on Redfin with no indication. There was another that had the most crowded open house we’d seen and then it disappeared from the MLS completely on the next business day. We weren’t making an offer on that one, so no idea what went down, but I’m sure the house changed hands.
