If you 
read the OP, you will see the coach did more than 'nothing' once in LBT:

 I think here is where the 'verbal obstruction' theory comes into play.   If the HC yells this from the dugout, no penalty.  From 4 feet inside LBT, calling it is  a punishment of stupidity.  I'm not arguing the point, but I can see a logic to this course of action.
I don't for a moment believe this actually happened, but it could be turned into a useful hypothetical discussion nonetheless.
