Right click Pivot table, Properties and change Destination cell. See Pivot moved. Undo. See it doubled. Another Undo removed duplicates. Not when moving with drag&drop.
IIUC there was no Layput in OO. Later in 3.x it was added so move via Destination was possible. But move would duplicate pivot. This was fixed in 5.2 with bug 89308 so that move works. But Undo remained.
