Yes the picture is reversed
If the uniform was reintroduced it would enable Bridegrooms and Best men to wear the gold/blue over the jacket sword belt rather than the 'normal fitting' (under the jacket) sword belt that they should wear with No1 SD (the guard of honour can wear the ceremonial belt as they are required to draw their swords). Mind you, most Bridegrooms tend to ignore the dress regs and just go with the one that they think looks nicer.
