When the LoopNode begins executing, the tokens on the loopVariableInput InputPins are moved to the corresponding loopVariable OutputPins before the first iteration of the loop. Source Unified Modeling Language 2.5.1
If a LoopNode has loopVariable OutputPins, then it must also have matching sets of loopVariableInput InputPins, bodyOutput OutputPins (owned by Actions within the bodyPart), and result OutputPins. Source Unified Modeling Language 2.5.1
