Or maybe it's not diving.
People often see perfectly natural reactions as diving. Look, ice is hard. Falling hurts, even with equipment. It's not like grass. People don't dive for fun. Not only that, but if you're losing your balance and trying to regain it, you can look like you're embellishing when you're actually trying to stay upright.
Not only that, but snapping yourself back is a natural reaction, even if you don't really get hurt. For example, when I'm walking and am stepping into something, I'll kick my leg back and stumble or fall down, even if the impact wasn't enough to do so. It's a reflex.
You can't even tell whether you're hurt before you do that. It happens before that registers. Reflexes aren't conscious.
Now, it's of course possible that there's some diving, but I feel like the vast majority of the time, people just don't understand what it's like to have a stick approach your face. Your reflex is to dodge it, and you might fall down doing that. It's not diving, it's normal. You don't want to risk actually getting hit by it.
