Two observations can be made. It is easy to determine which 'double' rainbow shots are fake. Secondly, the mechanic by which this occurs is not rare - it happens most times. However, it is relatively seldom that an observer is in a position where they can observe the second rainbow - let alone a full sky rainbow.
Discontinuities and anomalies are commonplace in these type of shots - in older cameras this is exacerbated by lens errors, but more frequently it is caused by raindrops appearing at white line noise.
A little like a human being reflected by a mirror - the second image strength is dependent on the light falling on the original. but it will still be a mirror reflection. Any injury or defect in the original may be magnified in the copy.
As for myself, I have fallen a couple of times in the field recently, re-tearing the injury that killed me briefly a year ago. That this copy of myself is less tangible is probably simply a sign of impermanence.
