The pop-up window might be useful if it actually showed any geometry that you could select as an accurate reference (see "proper 2D CAD" 
)
As it is, it still gives you no more accuracy than if you just dragged the pasted item by eye.
Mind you, I've recently been obliged to change from AutoCAD LT to SolidEdge for my 2D CAD and while there are certain nice features in SE, one that I'm desperately missing is "copy with base point". When implemented properly it's incredibly useful.
