Another idea for why. The finger insertion is also part of the routine exam for colon cancer , ie looking for blood and getting a stool smear for the instant reaction test slide. Not necessarily a dre, but since they're there.......
The DRE evidently isn't exclusive for prostate exams. There's other things , such as bowels, etc.
