is wrong, though a common misconception. That's where the shirt sleeve should fall. The jacket sleeve should fall about 1 cm short of that.
In the picture, the guy's sleeves are according to the (false) rule stated above, and the shirt sleeves in particular fall in a very unattractive way over the back of the wearer's hand. It's particularly notable on the hand, which isn't carrying the briefcase. The shirt should end at the wrist, in a very clean line.
