What does safeAbs protect from?

What does safeAbs protect from?

It protects from reverting in the case we've reached the negative bound (which doesn't have an exact positive opposite) I'll add a comment about it

EDIT: it's the other way around. Instead, safeAbs does revert in the case we've reach the negative bound
