8-6-14 R1 crashes into fielder

[rafking]

Can someone provide more context on this rule?
Fed. 8-6-14 page 67
"A runner is out when a defensive player has the ball, or is about to catch a thrown ball, and the runner remains on her feet and crashes into the defensive player. If the contact is determined to be malicious, the offender shall be ejected. An errant throw drawing the defense into the path of the runner is not interference. Penalty - The ball is dead and the runner is out. Each other runner must return to the last base legally touched at the time of the interference."

Let's say the runner is not malicious at all, just forgot to slide. Crash happens. Again, not malicious at all

A. Ball arrived before runner. No slide. Crash dislodges ball. I want the play to continue with a no call.
B. Ball did not make it before crash. I could see obstruction.

In reading and re-reading this, I think the key sentence is "errant throw...". Basically the fielder should not be in the way of the runner without the ball. If so, then easy obstruction call. I guess I am having a problem with a non-malicious crash with a called out.
