Coverage code vs Action message

Hi,

I would like to understand how the system creates action messages works when coverage code period is 1 day.

When I look at Net requirements there is 1 Purchase Order where there are 2 actions for the same Requirement date and To.

These actions both peg to different demand, but the question is because we have selected a Period of 1 day, should this not create 1 action for quantity 2, vs. 2 actions for quantity 1? Those 2 actions are "postpone"
