Of course, this is just for the humans and $httpBackend and _$httpBackend_ are different variables. But the injector function tries to figure out which service to inject based on the argument names. In this case, it ignores the underscores to make it possible to assign the inner scope _$httpBackend_ to the outer scope $httpBackend and use it somewhere else.
