I'm with shifty on this one.
I can see comparisons, while KP was "dropped" he was dropped for disciplinary reasons for inappropriate actions. He wasn't dropped for poor form or to give him a rest, and he was deliberately not picked for the T20 squad despite his u-turn and making himself available for selection for all forms of cricket.
it is effectively a ban, just hasn't had a length attached to it, quite probably because the ECB don't want to ban him as it will probably make the situation worse, and are hoping to resolve it quickly.
Call it "dropped", call it "frozen out" (temporarily), it all adds up to being disciplined/banned. It's like suggesting various Liverpool managers have "left by mutual consent", you can bet your bottom dollar they didn't want to go and yet did not have any say in the decision. So effectively they were sacked, forceably ousted from their position.
