Yes, "even further" means "even more" or "much more", and usually refers to someone doing something more than the previous person. "Further" can refer to physical distance, or in this case, it can just mean "more". Ex: I walked far, but she walked even further. Ex: The professor answered my question and then continued to explain it even further.
