Can the CLKUSR pin be used as both a configuration pin and then a user I/O pin after the device enters user mode?

Environment

BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description If you have enabled the CLKUSR pin function in your Quartus® II project, it cannot be used as user I/O once configuration is complete and the device has entered user mode. Only if this pin is not enabled for use as a user-supplied configuration clock, can it be used as a user I/O pin.
