Interesting, it must be fig 5. Move one stand center to center, then maximise the frontage. I have not got the full wording here, but I'm sure that is the case to avoid manovers where you try and charge only 1 or 2 stands. I know your example is slightly different as you are talking about LOS of the last stand. I'm pretty sure if 1 stand has LOS then the whole unit can charge and get into base contact (maximise the frontage).
