question concerning the doc of subversion r12903

You wrote in the documantation of subversion
file:///home/tfoerste/trunk/doc/book/book/svn-book.html#svn-ch-4-sect-7.2 :

"$ svn copy -r 374
http://svn.example.com/repos/calc/branches/my-calc-branch \
                  http://svn.example.com/repos/calc/branches/my-calc-branch

Committed revision 376."

My question:
Is it correct that the source (SRC) of the svn copy command is exactly
the same as teh destination (DST) of the command ?

Thanks for an answer

Sincerely
Toralf Förster
