Which sets the contents of buf to { 'H','E','Y',' ','G','U','Y','S' } and doesn't destroy the world. But because it ran out of room, it couldn't store the null terminator. Meaning buf[] is not guaranteed to contain a proper string after you do strncpy, so trying to use it as a string could cause undefined results and possibly blow up the world. So to be really safe, you do:
Which sets buf to { 'H','E','Y',' ','G','U','Y','\0' }, which guarantees the buffer is null-terminated whether strncpy ran out of room or not, and does it all without destroying the world.
