Union Flag Design Secret

At some point the British decided they needed to come up with an idea of how to let other Brits know that they were in distress but not to let on to Johnny Foreigner that they were in trouble so some bright spark came up with the idea of flying the Union Flag upside down.
Obviously their thinking was that unless you know what you are looking for, the British Flag is almost identical whichever way it is flown which was fine when you know but can cause a problem if you don't.
Fortunately for the hard of thinking, the right wing chose to hang the English Flag from lamp-posts all over towns and Cities to try and intimidate the non-English and even they with the few braincells they have rattling around in their heads couldn't get that wrong but more and more it is the British Flag we are seeing now with rain dripping off it while it wraps around the post because they may live here but England, United Kingdom and Great Britain are the same thing to them.
The problem with the England flag is that, despite it being very, very boring, it is mostly white with a red cross and as the morons have Zip Tied it to the Street furniture, they will be there for years over which time the red will become weathered and fade and what we will be left with is streets full of white 'Surrender' Flags which is probably the last thing the people who bravely anonymously abuse anyone who isn't White English intended.
Anyway, back to the Union Flag which is comprised of the Cross of St. George (England), the Saltire of St. Andrew (Scotland), and the Saltire of St. Patrick (Ireland) but doesnt have any Welsh in it although there was attempts to include the Dragon on it but everyone decided it would be far too hard to draw so never bothered but as flags go, it is a nice colourful one in a nice design but it does have a cunning design secret put in especially for the distress signal as mentioned above which almost everyone gets wrong.
If you look at the Irish part, their cross is off centre which creates a wider strip of white down the left hand side and the flag is flown with the widest section of white closest to the flag pole, the Military call it 'The Snow on Top' for some reason but if you see a British Flag flown and the thinner part is closer to the flag pole, then it is actually a sign of distress, usually along the lines of 'Help, a complete ignoramus hung this'.
It could also be a clever ruse that they know it is a distress signal and they are signalling that the country is now  swamped with non-White people coming here and doing the jobs we don't want to do and paying tax to the Treasury although that would take more braincells then they posses between the lot of them so it's very, very unlikely.
