In short, the keyboard knows that you typed something wrong, and corrects it for you. Cool…

When you tap a key on the touch keyboard, we detect the coordinates of your touch, and we can map it to the geometry of the keys. But as your fingers move about across the glass, your press is likely to migrate outside the boundaries of the key you intended to touch. If we relied simply on the geometry mapping of the keys, you would see a lot of errors … consider the example where you are typing the word “the.” If you type t then h and then touch between the e and w but slightly more on the w, the touch model adjudicates this, knows that t-h-e is the common character combination in English rather than t-h-w, and appropriately outputs the e. But if you touch the w fully, the keyboard respects that input and assumes you know best.”
