Assets can be included in more than one Collection. You can see all Collections a set of assets belong to using the “blue light” indicator in the Collections panel. You can also see what collections a selected asset belongs to by observing the check mark in the Collection panel.

You can also find out what containers an asset is in by double clicking on an asset to open the "asset view". The "Related" panel lists all Folders, Collections, Projects and Workflows an asset is a part of.
