You should have done:

mv -u /tmp/dirA/dirB /dirC

This will put dirB as a sub directory of /dirC.  The only reason it
worked the first time as you expected was because /dirC/dirB didn'e
exist, so it realised that you wanted the directory moveing.  Once it
already exists, it assuems you want to move the direcory into the path
given in the second argument.

I haven't explained this vey well, but I am sure man 'mv will'.
