Why, when ATC give a conditional "After the landing Easyjet Airbus A319...." do folk readback "after the landing aircraft...."
Could it be that there is absolutley no requirement for pilots to have any idea of what an A319 looks like or even what an easyjet aircraft looks like.
Therefore when given a conditional they will line up after the first aircraft to land..........which is why you have to limit it to the first aircraft to land.

The instruction to squawk ident is a mandatory readback item everywhere. The reason is as gonzo says and you should look up the official words used to describe the procedure which are along the lines of observing an ident from an aircraft
which has acknowledged an instruction to ident.
