Obviously Malaysian Airline is still unwilling to tell what they really know ( or they still don't have a clue what honest and timelycommunication is ). Why did they insist for more than 20 hours that the flight is "just without communication".
These story with the 2 passports is another BIG mystery.
Both PAX ( pretend to be ) are European and the names are European.
So the Pax must look European!
Did MH do a passport check and name verification at check-in /boarding ?
Normally one-way tickets raise questions at security ( SSSS in the US , in Europe they are more discreet ), why not at MH ?
In AMS the pax would have to do the Schengen Area immigration ( where stolen passports would definitely flag up ), did they never intend to continue beyond PEK ?
For China Austrians and Italians do need a Visa for China, so they would not be able to "disappear" in Beijing. Why didn't they take the direct flight from KUL to AMS ?
Too many open questions, zero trust in MH communication
