Yes because antimatter and negative matter are different things, although I’m unsure if anti-negative matter is expected to exist or not.
So I’m kind of confused about this experiment because I thought this was already known.

I wouldn’t have thought it would, since from my recollection antimatter is distinguished by having the same mass but opposite electrical charge, which shouldn’t affect how it responds to gravity. But it’s always good to have confirmation.

It shouldn’t, based on our theories, but we know something is “off” with gravity. QM and GR fundamentally disagree on its nature. This is one of those baseline experiments to confirm what we are assuming is true actually holds. It’s also an absolute bitch of an effect to detect and measure.
