Sorry for the accusation Old Boy! As an LACC South-banker was misunderstanding the reason for the restriction (just look at the timing of my last post for my excuse!)
However - I still stick by my point. In your case you've done what you can to comply with the "book". If the next controller continues the descent
they are now responsible for any separation that may be eroded if the pilot no longer complies with your restriction. If it was me on the other end I'm not sure you'd get a phone call though! May be too busy giving avoiding action
