The Funnel Stage can operate in three different ways based on the funneling method: Continuous, Sequence, and Sort. These methods determine how the stage handles multiple input links and produces output.
This is Pega/case-management terminology: a Funnel Stage (a stage that can be entered from multiple prior stages/paths) is documented as being able to operate in three configurations, distinguishing it from a simple linear or parallel stage. The other counts (Four, Two, Only one) don't match the documented modes for this stage type. This is a fairly obscure platform-specific fact rather than something derivable from general reasoning, so it should be taken on the strength of the source material it's drawn from.
