Newsflash: Do builders “sell” homes to themselves to raise comps?

I was looking at some sold listings in an area, and noticed one particular new build that sold for the highest in the area. (6000 sqft new build, 1.6 acres- pending and sold in a day by a realtor as shown on Zillow for over 2 million. (Highest comp and looks like others in that particular new build neighborhood listed or selling (but after sitting for a while?) for 950k-1.6mil MAX (however I guess other homes in nearby more established areas do support those figures). I was curious and checked the title info and noticed that the owner of the land from before it was built was an LLC, and then it was sold to another LLC that was a different variation of the first and showed owners with the same last name. Any thoughts on what’s going on? What does “SOLD BEFORE PRINT” mean and are these just people selling homes to themselves to raise comps or potentially something else? Is that a common thing?
