I noticed that bots developed this strategy of using salve while being hit by the tower. Humans used this while tower diving in several games to kill a enemy with low HP. Casters mentioned that - it was first used by OpenAI but I have no way of confirming that.

It's not. The change is from some versions ago. Now salve and clarity can only be cancelled by another hero (or roshan).
