CoverageView allows to setup a "Coverage" on top of other ones from the same store. As an instance, you may setup a "wind" coverage on top of 2 single banded "u" and "v" different coverages.
When asking the CoverageViewReader for the imageLayout, it should take care of returning an ImageLayout which is compliant with the returned coverage. In that sample case the sampleModel should be made of 2 bands instead of 1 (1 is reported by the underlying ImageMosaicReader delegate since the underlying coverage are single band).
