Remember that the right-hand side is the "position of Honour" - if you see military people walking about in uniform, rank should increase as you scan to the line's own right (your left, as you look.) For instance, a non-com and a captain walking down the sidewalk would have the captain to the right of the sergeant, and the captain would also be a half-step ahead.
The blue field is a reference for the top of the flag, and is therefore kept its own right or its own top.
When displayed in a group, the US Flag belongs at the top or to its own right. It may be displayed at the top of the staff, elevated at the right end of the line, or may also be displayed in a "fan" pattern with the Ensign in the centre and elevated slightly above all the rest.
Flying the flag inverted is a signal of distress. Striking the colours at sea and inverting them is a signal to any observer, and can also be used to indicate a field post in distress if it is expected to be observed by someone in a position to offer reinforcement. An inverted flag is equivalent to broadcasting "Mayday" on the radio.
Remember that Honours bestowed by position are relative to the object/person honoured - it may look backwards to you, but it is simply a matter of perspective....
I explained this to my wife recently, and she noted - correctly - that I always have her to my right, but the reason for that is twofold. I also like to keep my left hand open, being left-handed....
