Sounds like he's talking about the Single Wire Multiswitch. Search around for SWM, it's pretty cool. They also have a new dish with the SWM built into the LNB so you'd only need 1 wire from the dish instead of 4. Check out SWMLine. The question that's left is just how did they do the CATV install, splitters or home runs to a closet? Hopefully they have wideband splitters because the wrong splitters behind the wall could cause issues.
