Alan Mulally, Boeing's head of the unit, said at the start of the strike that it may cause delivery delays that would give Airbus SAS an advantage in what is the strongest commercial aircraft market in five years.
Alan Mulally has knowledge in what can effect Airbus SAS, which is not a company he works for. 
He is the head of Boeing, not Airbus SAS, but he does have knowledge about it. So, this is correct. However, the system found it difficult as it may appeared to say he worked for Airbus SAS, so it found it incorrect.
