Cheers for that.
So I guess Kus and Summers were 'done' under (e), as they moved forward the ref couldn't press the button. Of course he could have, but chose not to! Had he done so, he could have warned the said riders for moving, but chose to exclude them. The only thing is of course, if Lindgren did touch the tapes (as I thopught he did) he should have gone as well, as Tully had been, a few heats earlier!
