I think it’s important to differentiate between a single line of passengers going through immigration and the holding areas for flights which have arrived.

As multiple flights arrive, the passengers are brought to the arrival area and loaded into holding areas which are in lines . There are four or five of these holding lines which are areas to keep passengers and avoid over crowding in the baggage area.

There is not one single line for all passengers heading to immigration. As each flight has their luggage loaded onto the baggage carousel, the holding area for those passengers is released to the immigration line.

If you only have carry-on luggage, you may ask arrival agents if you may proceed to immigration and therefore bypass the holding areas and quicken your time at the arrival area of the airport.

That is the way I understand it. Hopefully that makes sense.
