Think of it like this:
You fly a crabbed approach. It's easy to do, doesn't upset the passengers. At some point you need to kick it straight.
If you are a Sky God you kick it straight 5 microseconds before the mains hit the hard, but for the rest of us what happens is that you straighten up at about 6 feet and immediately begin to drift off the center-line. So a bit of into wind aileron keeps you straight. After a while this becomes instinctive - all you do is fly down the center-line ........... there has to be a bit of wing down in there or you'd be going somewhere else, but it isn't something one thinks about.
It's the same as everything else in piloting: you need to learn a method to get you started. After a while all you do is fly the thing straight at the runway and down the center while you're juggling the loss of height, aiming at the threshold, getting the speed & attitude right ............ easy after an hour or two .....
