Jungle: Bug or Intended?

I know I cannot be the luckiest guy in the world. Often times while jungle the burn from the jungle item or the nuke from smite will leave jungle camps at 1hp and then just fizzle out. This cannot be a coincidence, it happens too frequently, and I've been watching streams of Jungle mains where it happens too. Often these streamers say nothing of it, whether they think it's a coincidence or not. It leads me to believe that the this is working as intended, but it has caused me to lose many contested scuttles or dragons; the HP literally sitting at 1hp, not 2, not 3, not 50, just 1.

This only happens to:

Large Raptor Large Wolf Red Buff Blue Buff Scuttle Dragon

Though I suspect it also happens on: Large Krug Baron

and only when under the effect of:

burn

If I have the DoT from Red the Red Buff will tick away the last HP from the Jungle camp boss.
