Being the guy on the ground who twiddles the pots on these things (now I hammer the keys on them!), Localisers have more output power and are lower frequency, therefore have more usable range through signal strength. I can only presume that glides are intercepted from below as you flyboys establish on the Loc then turn in/line up which is best practise really.
One thing for me though is why headset-chair interfaces (ATCO's) say "descend with the ILS" now and not as before "descend with the Glideslope"? Strange!
Oh and sidelobes are really well supressed nowadays so 6 or 9 degree approach should be impossible now. Anyway I hope the driver notices that something was awry if he did descend at that rate!
