The writers may well be just quoting lowest denominator (MTB I suppose?). OTOH, a bit more searching and I'm hard-pressed to find anyone stretching lifespan to 8-10,000 miles.
If you search automotive pads, you'll get something of the following:
"average lifespan of brake pads between 25,000 and 65,000 miles...." "though some people will have brake pads last beyond 80,000 miles...." While it's impossible to give an exact number, the 40,000-mile range is the general mileage to keep in mind when planning for vehicle maintenance...."
That is a rather big gap regarding miles for a set of pads, that is assuming it's referring to the front only. Under normal conditions & with commonly designed purpose; Rear pads do not wear as frequently.
As to clarify the point; The expectations for pad & rotor replacement is a "YMMV" greatly. A logical & common understanding of the system may aid in developing what to expect out of brake pad wear.
