Its pretty easy to see. There are some surface patches (from the ISOTRIM component) which genetrate Triangular patches, or patches with only three corners towards the poles of the surface. Thus when you explode these patches, one might not have the fourth corner point, hance why you would get a warning.
Try it with a sphere or other surfaces with poles and you will see the same thing...

Bingo!
Orange is just a warning... It doesn't mean anything is incorrect.
Also, the warning message should give a hint as to what is causing the flag.
