I did a quick search of the web and the following link demonstrates what Harvey is saying.

Con, Geoff et al,
 
I've always thought the open wing patterning was reminiscent of a Sunbittern (not that I've ever seen one of them in life!). And my understanding there, based on David Attenborough DVDs, is that it is a bluff tactic used when threatened. I think HANZAB says something about this in respect of Painted Snipe?
 
I also wouldn't discount a possible connection to reproduction/sexual selection given the role reversal in this species.
 
Just thoughts.

Yes Con  -  The pattern is curiously reminiscent of a Barn Owl.   g

Geoffrey
The ones I have seen flying were not fast and furious like Lathams Snipe but rather slower and more laboured. Plus, unless disturbed, I assume that they prefer to fly at night. If these two add up then one possibility is that the patterns are good camouflage for flying in poor visibility.

Haven’t seen those painted-snipe for a few days.  Maybe gone.  Reflecting on the views offered when they were here, I am struck by the unusual butterfly-like quality of the wings.  In the below, you might thing I have flipped the images, but they show the extended left wing (L) and right wing (R).  Therefore the elaborate pattern of the left forewing is completely obscured when the wing is folded (right and below).  Coloured arrows indicate roughly what I take to be the corresponding parts of the wing, eg the yellow arrow shows the ‘vermiculated’ parts  (are they ‘secondary coverts’).  One wonders what purpose is served by this pattern  -  perhaps the enhancing of the bluff display, perhaps something related to reproduction (although this is a female).  The green arrow shows the rear-looking eye, giving 360 vision  -  a capacity lost with the kind of wing extension shown on the right.
