The problem is, they didn’t learn anything after they jumped.
I assume you mean ‘they didn’t learn anything by jumping’, which doesn’t seem obviously true to me: They could have made predictions in the form of “when I jump, I will feel X” or “when I’m no longer in a position to plausibly feel responsible for taking care of X, I will feel Y” or “when I am certain I will die, I will feel X”, and had those falsified.

I guess “didn’t learn anything relevant after they jumped” would be most accurate.
Unless they actually killed themselves for a few seconds of relief.
