correct, but the closer you are the stronger the signal will be, and the more signal reflection you will have, so you will still have a useable signal, even if each side's antenna is not in the focused part of the beam. Plus the beam widths are not hard edges, look at a antenna RF radiation patterns in the specs and you will see that there are significant amounts of RF energy being pumped out in other directions beyond the advertised beamwidth. look at page 2 of the PDF linked below for an example.
