'Perhaps you are correct, but if there is a clearly defined holding point then why not just say "hold at X" instead of "hold short at X"?
Perhaps the "hold short" instruction should be used only when there is no defined holding point?'
Completely agree with you. A certain large UK 'northern' airport uses 'hold short' liberally and clearly niaw the CAP definition (and also shows little compliance with the new ILS phraseology, I should add).
