It probably has to do with the pilot's flame sensing capability.
Not sure how YOUR particular furnace, off the top of my head, senses the pilot flame (even though I have worked on various Heils, Amanas, Goodmans, and many others, and one can get mixed up trying to remember the differences in them). Either it will have a metal flame sensing rod that is about 2 1/2 inches long or so, that requires getting polished up with fine steel wool or a scotchbrite pad,...
... or, if you have no such sensing rod, you need to polish up the metal associated with the pilot assembly that the flame would be touching; it may be the hood. And sometimes the metal parts of the pilot assembly are in various pieces held together by screws that can be rusty and a bad connection can form at those joints and screws, and not be able to complete a circuit properly to ground at the control board. Everything involved must be free of oxidation and/or rusty/bad connections.
Or the pilot flame is not tall enough to reach what senses the flame, due to a restriction in the very tiny pilot orifice down at the very end of the pilot tube by the hood.
On your control board you shoud be able to identify what is in the pilot/burner area by the wires that head in there and where they plug into the board and read what the abreviations say at each spade connector on the board.
