I'm sure you can imagine that if the chassis is softer, it is making that "virtual" suspension arm between the centre of mass and the tyre softer. A softer suspension arm acts like a softer spring/damper unit. Hence the feeling of more "grip" from a softer chassis.
I dont quite understand this concept or the use of 'softer'

Then are not the same an are almost opposite.

What is 'softer'?, assuming the same thickness chassis, removing a brace from the chassis(solid to split block) doesn't make it any 'softer'.If you go to a split block in the front from a solid block it allows the front end to twist more under cornering forces in relation to the rear of the car, it doesn't make anything softer
