You don't seem them at the exact time they need to be on screen, whatever than even means, you see them at time they are received by the monitor like in the uncapped case and you also get tearing like in the uncapped case. Unless you have a form synchronization on you always get this behavior no matter how many frames per second the game runs at because the synchronization rate does not match the cadence of frames being delivered.
In this situation not only you get comparable input lag with the vsync case but you also get tearing, so you stand to gain nothing. The only reason you might want to do this is if the game you're playing can't quite hit 60 and you don't want stutter. As a matter of fact some games, especially on consoles are doing this, whenever the framerate drops below 60 they switch vysinc off. hat's why I said this hardly achieves anything in my initial comment, hopefully now you get it.
At first I thought you just refused to read but know I now you probably have some literacy problem as well, you are supposed to be proofreader as well, imagine that. There isn't a single place in those comments where I said that input lag and frame times are the same thing, just that lower frametimes naturally lead to lower input lag which is 100% correct.
