If you like to follow them run into the next aggro and get yourself killed too.
I am with Mac'Od Bitty. Homins are in coma then and hence cannot walk.
It means a sharp break from their previous life and as such it should also be reflected by the options your comatose body offers.
Being a lazy person, I do understand your wish to also have the follow option to make it easier to follow the person in question without any more clicking once they get resurrected.
