TL;DR
Siding clearance is the vertical gap manufacturers and code require between the bottom edge of cladding and surfaces that hold moisture: typically 6 inches to grade, 2 inches to roofs and decks, and 1/4 inch above flashing. The gap keeps splash-back, snow, and standing water from wicking into fiber cement or wood and rotting it from the cut edge up.
