I didn't mean that, read it again. 'Touch' was used to illustrate the fact that you can imagine something being infinitely close to something means it touches it. As in, as the difference between 0.999... and 1 becomes infinitely closer you cannot possibly measure and state it. They are therefore not consecutive, but the same number; they are touching rather than the shortest of distances apart.
So, taken in this sense, 1 and 2 are consecutive, but not touching.
...Just look at the wiki, that'll make sense.
