From what I understand, the problem is as follows:
Trulli got off the track under the safety car. Hamilton couldn't break and at that point couldn't know if Trulli would be able to get back onto the track or not.
He correctly overtook Trulli.
Trulli made it back onto the track, taking the position 4 behind Hamilton.
Hamilton saw this and the Team (as far as read) not fully aware of the rules during safety car, instructed Hamilton to let Trulli pass. How far Hamilton went to let Trulli pass or not, I'm not sure, but obviously Trulli either took his slowing down as a gesture for him to reclaim his 3rd position or he thought Hamilton had a problem.
He then overtook Hamilton under safety car.
The stewards saw this and punished him for that.
I can see this going both ways. Either Hamilton forced Trulli to overtake in which case, Hamilton should be 4th, or Hamilton didn't and Trulli reclaimed his position against the rules. He then should be punished.
Hamilton should be at worst be able to keep his 3rd or 4th place. He wasn't the cause of the situation after all and acted either on behalf of his team which instructed him in what they thought was the most sensible thing to do (perhaps let Trulli pass again).
