Field Goal Attempt Question

[HardHat Ref]

A 4th down field goal attempt by K1 from A's 10 yard line crosses the goal line hits the upright and falls to the ground in the endzone.

As an official with 2 years under my belt, I have only worked freshman and youth games and thinking about it have never had a field goal attempted.

As I was studying the rulebook, I came upon this scenario.The ruling as I read it, is a touchback.

6-3-3
Art.1 ... It is a touchback if any free kick or scrimmage kick,
b. Which is a three-point field goal attempt, in flight touches a K player in R's endzone, or after breaking the plane of R's goal line is unsuccessful.

I thought A would start a new series from the 10 yard line, but after reading the rulebook it seems to be a touchback. Am I interpreting the rulebook correctly?
Thanks
