I think it has to do with familiarity. It just felt unnatural to me as the other lefty bolts have the safety on the left.
Using your logic, why do NONE of the right handed bolts have the safety on the LEFT side?
On mine as I recall I had to shift my hand because I couldn’t disengage the safety from my firing grip. On a left side safety say a Remington I only have to move my thumb. It also just looked weird to me other than that it was a great rifle.
