The safety switch turns off the fuel pump when the engine is not turning over. The reason to bypass is to have a manual way to test the fuel pump circuit when the engine is not turning on at all. Although, there are better way of doing that than to provide a bypass ground like that. But, that was a lot of work that person went through to implement the switch so there must be other reasons for it.
