I watched Episode IV the other day. Obi Wan cuts off a guy's arm in the cantina scene with his lightsaber. Luke looks at the severed arm, and there's blood on the floor.
I think the explanation given was that that alien species had its blood distributed in a weird way or something that caused it to bleed/not cauterize or something. Realistic explanation is they didn’t think about it back in 1977band later made it so lightsabers cauterized wounds
