I'm sure you do, but I'm not entirely sure what you're talking about. hoc habet was a colloquial term used among spectators in the arena when somebody was hit, and your reference even confirmed that. The connotation "it's over" when somebody has received a lethal wound is rather obvious, but that's all both AoM and your source were saying.
Have you seen the Plautus examples and Loeb's interpretation of Terence's habet which Donatus cites?
