continue approach, can be useful sometimes, apart from the points made above it may be continue approach you are number 4, so helps create a better situational awareness, just the same as a pilot reporting on frequency and his range from touchdown, most units have a ATM so know how many miles you are, but the other aircraft dont, aircraft at the hold can become aware of the likely hood of getting a line up clearance, someone landing ahead be more aware of need to vacate quicker etc
