Adding oil to engine is not rocket science and the dip stick is such a crude measurement device that 1/4" is well within the tolerance. BTW, we do not dispense oil using a precision device down to milli-litre.

The most practical reason? Because if your engine failed for an oil related reason and was overfilled Mercedes would probably not honor the warranty. Their warning is very clear.
I am not sure why all the drama. The advice was to make sure that the air filter was clean in this particular situation.
Yikes.
