Jan rides a lot more miles than I do (remember that he's the only person to have ever worn out rootboy's brass-wired tire savers) and is of the opinion that lower tire pressure *is* a method of achieving puncture resistance.

For example, he talks about getting 5000 flat-free KMs out of a pair of Grand Bois Hetre tires; the Compass tires are meant to be "Hetres that fit mountain bike wheels" so I would expect similar performance.

I still wouldn't commute on the Compass tires or any nice tires if you live in a scrap-metal yard, glass recycling center, or other pathological location. (Does Goathead Thorn country count as pathological?)
