Why should way B be based on way A? You have been there, noticed the new 
way and added it. Why should you put it one kilometer away just because 
there is a "copyrighted" way beside? If way B is next to way A in 
reality than it will always be next to way A on any map regardless of 
the copyright.

Otherwise no one would ever be able to draw a map, because then anybody 
who has already drew a map before can complain that you have copied the map.

OTOH that would be the solution to the licence question: Whoever has 
added the first node in OSM (Steve C?) decides which licence we use, 
because all other nodes are based on that node :-).
