Why are the IPL approaching England players?

The deal that I expected to be going on behind closed doors was that the BCCI would be asking the ECB for support in trying to put cricketers off joining the ICL - the rebel league. In return I expected the ECB to say that they would expect the IPL, run by the BCCI, not to approach any England players. This seems like a fair deal and what I assumed had happened. But Pietersen is now saying he's had several offers from the IPL.

I wonder if the ECB have done some poor negotiation, or if the BCCI have just ignored any deal?
