Different rule. In the OP, R1 is RETIRED, which is covered in the rule I quoted (12.19.5) and there is this:

12-9-11 When, after being declared out or after scoring, a base runner interferes with a defensive player's opportunity to make a play on another base runner.

There is no requirement of intent for a RETIRED runner, which is the OP:

F6 tosses the ball to F4 at second base to retire R1, who is now just jogging towards the bag. F4 then throws to first to make a play on B2, and the throw hits R1 in the shoulder while she's between the two bases.
