You are moving the selection mask and not the selected pixels. To move 
the pixels to have to copy paste them and then move the resulting 
"Floating selection" layer (set the move tool in "Move; Layer" mode (top 
line of icons in the Tool options).

From your screenshot it sees you are trying to make the symmetric of a 
line that you create using the path tool. May I take the liberty to 
refer you to my path-mirror script 
(http://gimp-path-tools.sourceforge.net/tools.shtml#path-mirror)?
