Objects holding a group of objects?

I'm a bit confused by this video. Alena says an object can hold a group of objects. But it seems like the "group of objects" is simply an array being stored within a single object.

Can someone please clarify what she is talking about when she says an object can hold a group of other objects and whether the group of objects is actually just an array being stored within a single object?

Thanks.

Think about it this way a folder is an object to hold sheets of paper (other objects) which is true of plain arrays too. But with the folder as an object you can write custom method to extend its functionality. I.e. a custom sort method to sort papers in order etc.
