Wire drawing is normally caused when the valve closes trapping a hard contaminant between the valve and it's seat, and the subsequent coolant flow then scours a line in the valve seat that allows water to bypass, even when the valve is closed.
Once the process starts, it is self perpetuating cycle of deterioration.
Hope this explains it.
