This a common problem with abstract art. I have seen examples of rotations over various angles. I also have seen mirrored reproductions in catalogues and even the wrong work being reproduced in publications, especially when the works are from a series of similar works or when the final work differs but slightly from a study and a photograph of the study is used as a reproduction. Sometimes it is even not possible anymore to establish the original title of the work due all the confusion and mismatches. I know of two art museums in the Netherlands who both claim to posses the same art work from a series, while the works are clearly distinct. I think I know which one is incorrect, and I did point it out to them, but they simply refuse to correct the title.
