Well the WOM or 1447(b) can expedite the entire process or to be specific case processing and a derivative benefit of WOM or 1447(b) law suite USCIS may ask FBI to expedite NC on your case.
Still technically "we" can't expedite the NC process, but force USCIS to expedite our case processing so that USCIS asks FBI to expedite the NC.
Same result but technically beating the drum at different positions to produce a sound/ music
I hope you will agree.
