They print both for the people who do not have lower than standard TO minimums. Jepp will make a "custom coverage" for you with just the airports and approaches you want. It costs $$$$ but I was down to carrying two Jepp books for the US at the prior job. Most small operators carry the regular or HP sets (just airports with runways >6000 feet, cuts out two books.) It's up to the pilots in those cases to know what applies. You pick the highest of the Ops Specs, what you have been trained to or what the runway allows.
