The .50/81mm combo was used extensively on PCF "Swift" Boats and 82 foot Coast Guard cutters during the Vietnam War.
According to Riverine: A Pictoral History of the Brown Water Navy in Vietnam (Jim Mesko), "Because of the way the weapons were sited it was not possible to fire both at the same time." (p.24)
I don't know for sure, but I'm guessing he means that the gunner could not switch instantly from the .50 to the mortar without having to re-aim first.
