I know this is not the explanation for the guy shooting high.
In most coordinated systems you note gravity as -9.81m/s2. There for using a simple displacement formula would prove you correct.
Easier put, ignoring friction coeficients, shooting down is (-), (-) and (-) = greater magnitude. Shooting up is (+), so (-) and (+) = lesser magnitude.
I do not have time to do the actual calculations right now.
