Back to Basics define MUTATION how & why?

While I am certainly No genetic expert, I have had quite a few mismatches within my Own Name results.
I have just read something that completely blew me away though.Apparently one man did a dna test and found he had mismatches to someone of his same name too.He was apparently from a heavily male family so he began testing all of the males he could get his hands on within his Immediate Family to do a ydna test. The results were absolutely astonishing...he had Over 8 mismatches within his Immediate male family line, which as he would have been told by any testing facility would have meant NO Match at all.
Since I had 6 mismatches to one man of my same surname (all but one of which were the rapidly mutating markers), I will now completely ignore those and consider these men my ydna cousins while certainly not as close as an immediate family, but a heck of a lot closer than one might be given the impression to believe.
I also have a new match to another of my surname and at 25 markers (their 37 marker test results are not in yet), we have 2 mismatches which I will also ignore.
Our families are all Ulster-Scots and all seem to stem from the same county in Northern Ireland before emigrating to America and several things in our genealogies are matching up as well (we haven't shared entire info as yet, we're still working on that).
So, this person's story really knocked me over.I figure if mutations in those numbers can occur within one family from grandfather to father to son to grandson to grt. grandson...that's pretty alarming.
Over 8 mutations off in one family. Whew!
