Gelly Scatter-Gather Iteration, In a single superstep, GatherFunction.updateVertex invoked more then once

Hi:
According to the code comment, in Scatter-Gather Iteration,
Gather.updateVertex is invoked once per vertex per superstep. But in my
programming, i find GatherFunction.updateVertex was invoked more then once,
is it a problem of the code comment, or a bug of Gelly. My flink version is
1.5.3
Does anyone else have the same problem?

Would you perchance have an example program to demonstrate the unexpected
behavior? Does this issue always manifest or are you only seeing duplicate
calls under specific circumstances?
