Unlikely you would think, that an aircraft would taxi into another one...
From WSSS airport charts:" Aircraft on TWY WA are not clear of aircraft pushback from aircraft stands C24 C25 and C26 until at end of pushback." The 380 came out of C23 but still infringed taxiway WA. Ground Control could well have rightly assumed that no conflict was going to arise because C23 was not included in the warning.

Reason: rethink.
