I have a decent amount of time on the NG. I have never seen or heard of this "problem" either. Close thrust levers during touch down, it's pretty much basics of flying any type is it not?
I did very occasionally, I think twice in ten years, have one thrust reverser fail to deploy during landing but then operate normally when recycled during taxi. Which is something I can't say I have seen on the A320 which has the same engine type.
