It does depend on destination, sometimes secondary checks are conducted at gates, well after security. Earlier this year travelling out of DPS (which has central security) to Australia, they were conducting secondary checks of hand baggage, and took away the water bottle I took from the lounge. They don't do that for DPS-SIN flights.
