Not really. Ultear's Magic didn't affect humans, but we were never told why. His Magic affecting humans simply means that his Magic's ability is altering the age of human beings. While Ultear's Magic's ability is controlling time, but not controlling the time of human beings (and other living things). It's incredibly difficult to explain what I'm trying to say, but I'll do my best. Ultear's Magic has the ability to do A but not B. This dude's Magic has the ability to do B but not A. Ultear's Magic not doing B doesn't mean that it isn't doing B because B is too powerful a feat for the Magic - that's just not the Magic's purpose. On that same note, if this dude's Magic can do B but not A, it doesn't mean that A is more powerful - it's just not his Magic's purpose.

Also, we haven't learned anything about this dude's Magic, so things may not be as they seem.
