Is the default "serial document workflow" really a majority voting workflow?

After looking at the serial document workflow in v5.6 it appears if the number of rejects exceeds the number of validates the document is automatically sent to request_update task. Which upon exit, if not cancel, sets the "index" counter to zero. Does the workflow then start from the top of the participant's list? Does this work if there is a even number of participants, let's say 4, and two validate and two reject?

Looking at the code again the workflow does not stop until the index count is equal to the number of participants or is explicitly canceled.
