"Ranged Touch Attack"

[Bushwhacker2k]

I notice, looking at the logs of combat, that when someone attacks, regardless of whether or not it's a hit it shows the chance to hit.

 

But, some attacks, like the giants' thrown rocks, don't show the hit chance and when they're avoided it claims a character has 'dodged' the attack, rather than the attack just missing.

 

Is this just tricky wording and it functions as a normal ranged attack- or does it actually function differently?

 

I wouldn't ask, but those giants are so accurate with their rocks and generally inaccurate with melee attacks.
