It's in the standard we are following,
http://www.opengroup.org/onlinepubs/009695399/functions/rename.html:

"If the old argument points to the pathname of a directory, the new argument shall
 not point to the pathname of a file that is not a directory."

http://www.opengroup.org/onlinepubs/009695399/utilities/mv.html:

"In the second synopsis form, mv shall move each file named by a source_file
 operand to a destination file in the existing directory named by the target_dir
 operand, or referenced if target_dir is a symbolic link referring to an existing
 directory. The destination path for each source_file shall be the concatenation
 of the target directory, a single slash character, and the last pathname
 component of the source_file. This second form is assumed when the final operand
 names an existing directory."
