A lot of reasons. If I've been pushing people around a bunch, I don't want to open UTG with many weak hands because they'll probably pick a good hand looking to make a stand with against the short-buy donk with a PFR well into the double digits (over a small sample size.)

Also, none of my ranges are absolute. If I open UTG, there still is a non-zero chance I have something like 78s.
