Hs version of jets ko play

[GPC2]

Case Book 6.1.8 SITUATION B: The free kick by K1 from K's 40-yard line: (a) is touched by R1 at R's 5 and goes out of bounds at the 8-yard line; or (b) is muffed by R1 at his 15 and then touched by K2 before it rolls out of bounds at R's 10-yard line.......RULING: In (a) and (b) the ball belongs to R at the inbounds spot.

I don't see much difference between the NY Jets play and (a) above. The ball was dead out of bounds as the result of R's action in both plays. What am I missing?
