I don't think it really can be explained. In the early games, Abe was inexperienced with his abilities. Therefore, when Abe depossessed a slig the backlash caused it to explode. In AE and MO, it shows Abe has more control over this as he is able to depossess Scrabs and Paramites without blowing them up, as well as the ability to pilot his consciousness (ie possession orb). As the story progresses, Abe chooses to blow them up. One less Slig to worry about right?
As to the physics behind it, I don't think Lorne and crew thought that deeply about it. I think they just did it for the lulz.
