Different things. Low HD creatures in 1e/2e had low hp because they were that type of creature. 4e minions had 1 hp to facilitate a *story*. They were less simulationist constructs and more storytelling devices.
And in a game like feng shui they were awesome. It wasn't until 4e that a mechanical devics was needed to create the one-shot kill, D&D never had that issue, and to be honest only really has at at low levels.
I understand the mechanic and its roll in creating dramatic scenes, in D&D historically it as been doe with lower level creatures where average dpa outstrips average hp.
