Ok, first, the timing light is useless to test camshaft/camshaft sensor alignment. Because in these cars, ignition is not synchronized with cam sensor, but only with crankshaft sensor. It's the case in Ford cars equipped with ignition distributor-less system.
Cam sensor is used only to adjust fuel injector synchronization.

He should have put cylinder #1 at TDC before removing the synchronizer, but Fuel injection synchronization doesn't require a such precision as the ignition synchronization. Fuel timing is not that important.
Because it's an indirect fuel injection, you don't care if the fuel injector open few degrees earlier or later than normal, the long as it finishes spray fuel before intake valve open.
It's why you don't feel engine symptoms. Maybe at 5500 rpm engine can ping, but not necessary if he's lucky. So the long as engine is running fine, he should be all right. No miss, no sputter are good signs.

The reason why PCM gives code for camshaft/crankshaft out of sync, it's because PCM is afraid that camshaft sensor is not aligned with crankshaft which result in important engine damage. But you know that the one who is misaligned is not the camshaft, but the sensor's synchronizer, so you don't care.
