This allows the OnPCDrop variable to get set correctly even when object placements have to go through the server first in order to gain a unique multiplayer index (mpNum).
Among other things, this makes it possible to roll marijuana joints in the popular mod "Tribunal Code Patch".
Previously, reusing the console's object selection code made it so using the same Ptr twice in a row was akin to clicking on the same object twice in the console window, i.e. the object was deselected the second time around. Additionally, that same code was setting key focus to the hidden console window, preventing players from moving until they activated another window (such as their inventory or chat window).
