Something tells me that if Darius didn't died, Alexander would steal him too and told him since they have the same mother now, therefore he's his brother.
Finally, considering who was Alexander's mother, i'm not really very surprised he would want other one.
Well to be fair to Olympias she was actually supporting Alexander all the time, and the trust was mutual since he appointed her regent while he was adventuring, but her character was at best difficult and guy like Alexander would probably like to put a good chunk of Asia between them.
