So he said overall the slight benefit of bringing the heating vents down to the floor isn't worth it in his opinion.
Maybe this is a holy war in HVAC circles. Playstation vs Xbox. Tabs vs spaces. Coke vs Pepsi. Floor vents vs ceiling vents.

Sounds like more work for them = faint reasoning to not do it.
The heat entering the room at the floor level and then rising is what causes convection and more even temperature throughout the room.
