^ agreed.
There was no water in that picture so it could not possibly show an overflow.
Personally I think they should be referred to as 'drainage' since it does cause some mild confusion calling them 'overflows'. But 'overflow' is already basically part of the language of this hobby so we are stuck with a good 'overflow' and a (extremely) bad 'overflow' and some mild confusion if both are referred to in the same thread.
