The decision makes sense. There's no way to tell exactly what's going on so everyone suspected is being suspended. Also, despite her passing Itachi's test, I'm wondering how Yoruichi will react when she realizes Itachi still doesn't trust her. After all, he only confirmed she wasn't under an illusion, that doesn't prove she's innocent since she could still be aiding whoever's behind this willingly. We know she's not, but Itachi doesn't and he still has good reason to be suspicious of everyone until the culprit is found.
