Decreasing code duplication is good of course. But you need to be careful that the two pieces of code are inherently equal and not just by accident. Because once you consolidate the code, for example like you suggest, and somebody comes along and changes `GOOD_NAME_FOR_MAGIC_CODE` to something else, without being aware that it is used in multiple places, he might inadvertently make a change he did not mean to do. Tests help, a good IDE helps (to find location where a symbol is used). But still, it's a fine line to walk.
