What should happen is that the Ctrl command executes if you press and release button 10, whereas the paste command would execute as soon as you press and release buttons 10 and 12, which would also execute the Ctrl command as soon as button 10 is released as part of that combination, as both commands operate independently of each other.
You could combine these commands in to a single command that triggers off of the button that is shared by both commands (button 10, in this example), and then while that button is pressed check whether button 12 is also pressed, so that if it is one set of actions executes, but if instead button 10 is released without button 12 also being pressed, another set of actions executes.
E.G.
Start Loop While : Joystick 2 Button 10 Is Pressed
Begin Device State Check : Joystick 2 Button 12 Is Pressed
Press Left Ctrl+V keys and hold for 0,06 seconds and release
Say, 'Coller'
End Condition - Exit when condition met
End Loop
Begin Text Compare : [{ACTIVEWINDOWPROCESSNAME}] Contains 'Vectorworks'
Exit Command
Else
Press Left Ctrl key and hold for 0,06 seconds and release
Say, 'ctrl'
End Condition
