If the hole that you drill is really off center, it won't fix that. But if it is just a little bit off it should compensate for that a bit because the seat lip cutter has a depth-stop on it. What that does is make the doo-hickey sit flush at the top which will also, presumably, make it be in straight. The hole doesn't have to be in absolutely 100% perfect, but you do want the new hole to be flush with the block and that's where the lip reaming effect comes in. Here, I found the instructions for you on the TimeSert. It's pretty easy to use, that is if you have the room to maneuver under there.
