What is the Square rectangle on the corner of an app icon?
Look at the picture. What does the black bordered rectangle on the Safari icon means.

Its not a rectangle. Its an iPad icon. It signifies you were looking at a website on another iPad in Safari, and can open it on this one now.
Its a Continuity feature known as Handoff. See here: link->Use Handoff to continue a task on your other devices - Apple Support
