I can't see this is happening! reprogramming a word in flash means 
erasing and reprogramming a whole 8KB block.

Maybe they keep SWI in flash and keep it there and when SWI happen, 
J-link will insert the correct instruction in the pipes and continue 
execution. If this is what they did, great job.
