You misunderstand. Sure that is a part of memory safe, but why is the much larger problem of running off the end of the buffer into something else not considered a larger part. In my experience the later is a worse problem (the blame for issues goes to someone else who's code is working perfectly correct and so they spend months trying to find a logic error before someone finally looks elsewhere - often the fix is just a random fix by those who are at fault and so the team will spend months more looking before closed as "doesn't happen anymore, no idea why". Memory leaks by contrast are hard to track down, but at least they leave obvious clues and so the blame doesn't go to the wrong person.
