at least psychologically. As the onlooker, my options are killing one myself vs. not saving the five, whom I don't feel personally responsible for their death. This is different from the options the driver face, which is killing one vs. killing five.
If I were that doctor, my options are closer to the onlooker's, so of course I would not kill the healthy patient.
From a utilitarian's point of view, the pain suffered from killing one person is so much stronger than the pleasure derived from saving the five, that most human won't do it. If you have a utilitarian robotic doctor which can sum up all the pain/pleasure, then I presume the robotic doctor might kill the one healthy patient.
