The collapse strategy language may be missing from the print friendly, but your editor screen capture is about the collapse strategy and your print friendly screen capture is referencing the end date strategy.
End Date Strategy is use to specify when, after the initial event passes inclusion criteria, how long you should consider the event’s episode before the episode ends. By default, if you don’t specify how an initial event should end it’s episode, then the episode will be defined as from the event start to the end of the event’s observation period.
