They were both marked "outdoor use only".

Why? It doesn't make any difference to me because they were going
outside, but it made me curious.

Who uses a garden hose indoors?

Anyone draining their water heater, hydronic boiler or similar.

draining my fish tank.

emptying a water bed.

when laying saltillo tile, saturating them with water can prevent them from
sucking the water out of the grout and staining the tiles. i've watered my
living room tiles using a hose (it helped that i replaced the baseboards
with cut saltillo tiles).
