It's not a trick suspension, it's a beast of a chassis with loads of downforce combined with the most efficient engine treating the tyres better than everyone else, but that doesn't sell so F1analis needs to invent some trick.
This comment doesn't make a lot of sense when you consider that most of the performance advantage comes from the low speed stuff where the aero effect is the least.
Traditionally a car unloads itself on the inside tires due to weight transfer in the corners. This is what limits the maximum corner speed (on top of the downforce). If you can use the suspension to push down on the inside tire, you keep load on the front inside tire during trail braking and at apex, meaning you can go faster.
It's obvious on the front axle, that if you make a geometry, and just boost up the power steering, you can load the inside tire in a corner without straining the driver anymore than usual.
If you have managed to replicate this effect on the rear axle (where the everything is passive), you could also improve the corner exit traction on the inside wheel as well. But would require very clever implementation.
I don't know what Mercedes are actually doing. But it's a possibility that its'a combination of many many things including aero, and suspension. Overall they have a great car.
