You have billions of identical copies of the DNA molecules probably, so it might matter less if there are some breaks or errors when you sequence, if you sequence very thoroughly.. even when sequencing fresh DNA you have lots of read errors, inserts and deletes.. (haven't read the specifics of this case but I'm sure the fidelity numbers are in the articles somewhere, would be interesting!)
