Regardless of what the regulations are, in Ams you can clear security with liquids not in a transparent bag, inside your bags, and also with liquids exceeding 100ml.
Just did this again without a secondary, there are clear information signs stating you need to leave liquids inside the bags, but you can only do this where the newer type of scanner is deployed. It's possible all scanners have now been replaced at Ams. but they used to have them only on one side of the airport.
