I learned to touch type with the home row thing, but I never find my fingers really going back to the home row, they just go to the next letter that needs to be typed. I guess with experience comes automatism, which in my case doesn't always involve going back to the home row after typing a letter. Or something.
I think it's quite common. I have seen friends type. And everyone who is commenting on this thread and touch types goes to home row only to take a break. There is no home row between two consecutive letters unless they involve letters on the home row.
