I'm looking at it from a lay scientist perspective with this. They're blasting it with lasers, it's internally unstable, things are flowing out of it, and evidence of negative mass is that it moved in direction different than expected. There's a lot of variables here that might cause that movement that have to be eliminated. Maybe they have but experiments like this leave me uncertain about the outcome. Note: Also, they should look for integer/floating-point errors in the measurement code while they're at it. ;)
