It's a good flavorful note too, instead of saying a monster is at half HP, it means you've managed to finally draw blood! Even if there's no mechanical importance it can give you the confidence to keep fighting instead of retreating "If it can bleed, then it can be killed! Let's keep at it gang!" That sort of thing.
I played in a 2E game where the DM kept track of everything, he never told you how much damage you took or how much damage you did, only that you hit or were hit. Now he'd let you know in a general sense of when you were getting low on HP or an opponent took significant damage or a critical, or in the event that we had no chance of hurting something he would drop us subtle clues. It really made for intense combat as he never said you crit, you took 18 points of damage, etc. It may seem heavy handed and took some of the fun away from the players by him rolling their dice for them, but because he was fair and descriptive it was actually really fun and added to the suspense. More trouble than Im willing to put in as a DM though.
