Instead, I would adopt the following language:
"If a free kick goes out of bounds between the goal lines untouched by an inbounds player of Team R, it is a foul."
The problem with that is FED has compounded case book plays and dumb IP rules, so Ralph's proposal works to fix the rule the way FED wants it called.
FED doesn't want the play where the ball is rolling in bounds and the returner puts one foot on the sideline and touches the ball to get a cheap KOB foul.
Case book 6.1.9C seems to only want to call KOB when the ball is over OOB territory when touched.
Case book 9.6.2C wants this play as IP, but it's unclear if they want it to offset with KOB.
Ralph's proposal eliminates the confusion and gets rid of that dumb IP rule.
Here's a similar one I've proposed:
Art 9 … A free kick shall not be kicked out of bounds between the goal lines untouched inbounds by R.
It is only a foul if the ball becomes out of bounds while on or above out of bounds territory. If it is kicked out of bounds and R does not accept a penalty for kick-catch interference on the same kick as in 6-5-4, R has the following choices: …
