Not that anyone else is wrong but it's also worth noting that if you block at the right time you won't get pulled at all. I don't think it's an immediate pull it happens 1 or 2 seconds after the fact. So there's time, if you don't panic.
Basically what you don't want to do is roll. Because the roll will happen then as soon as you stand up that's when the pull happens. Best to just stand still and block for a second or two, then cast forward momentum and run away from the follow-up.
