Yes, there is some extra stuff in the scene browser to make it kind of feel more like layers when working in there.

In the traditional kind of CAD layer system, when you assign an object to a hidden layer it becomes hidden since layers have their own on/off state separate from objects.

MoI doesn't quite work exactly the same as layers because in MoI only individual objects have an on/off state and not the layer (or style as it is called in MoI) itself. This is what makes it possible to have more than 1 organization view to work with objects, like both a Types section as well as a Styles and Objects section all at the same time, since each one works more by controlling a batch of object properties rather than each of these different mechanisms having its own private on/off states that would then conflict with each other. Like for example if you set all curves to be hidden under Types and then set Style=Red to be visible, that would then be 2 conflicting things applied to a red curve if the on/off properties belong to each Style and Type entry instead of it being a reflection of all the individual object properties.

But since some people are used to the layer mechanism where assigning an object to a layer makes it become hidden if the layer is hidden, MoI will kind of emulate that behavior when you are using the scene browser to assign the style.
