It does not work, at least not if you don't also include the Poor Man's debounce technique of throttling the loop or otherwise not calling the wasPressed() method too frequently.
It is fixable, but by the time you have done, it will just look like many other debounce code sequences.
I'll leave it to whoever cares to do what they need to see for themselves why it fails. It would take 3X the time I've already wasted spent to produce a lab report detailing the experiments.
This library shall join too many others at which I have looked closely until I throw them in the trash.
