Ok, ok... here's what I heard today:
Both of you are partly correct, as both these incidents (alleged??) happened to the same flight number, but on different days.
It seems (not confirmed, wait for the ASR) that last week sometime, an a/c had to turnback due to a thrust loss/shutdown of 1 engine.
Yesterday, another flight turned back, which could be the bleed loss described above.
Watch this space.
Later.
