That is sometimes true, but I think in this case it was just a gimicky saucepan set. Like many of these ads the 'solution' they are showing to the problem doesn't actually work any better. In this case they 'solved' having to hold a strainer and a saucepan at the same time by having a built in strainer that pivots as you pour the contents out. But with handles on both sides of the pot it makes it hard to actually hold and tip a large pan whilst holding it up. A freestanding collander in the sink and resting the pan on the side of the sink while you tip the first of the contents out and lighten the load seems a much safer/easie option to me. Or if it was set up like my mum's tipping kettle that has a stand so you don't have to hold the weight in your hands.
