This is what I thought as well. From what I know with a loose diff your car more easily gets wheelspin on one side and a lack of drive on the other. On low traction surfaces you easily lose grip on a wheel (in particular the inside wheel in corners), resulting in a lack of drive through/out of corners and depending on the track it may unexpectedly bite on a certain side. One of the things your car might (also) suffer from is a tendency to start fishtailing (in particular out of corners or on bumpy tracks) because the highest grip switches between left and right and back all the time.
Of course, too thick a diff will cause massive understeer on any surface. However,my rear motor buggy didn't show any more understeer with a 5k oil filled gear diff on high bite astro as compared to a ball diff, so you don't necessarily need to put shock oil in your diff like some setups suggest
