Just wanted to clarify a bit further.  As long as the "Current Capacity" exactly matches between the source and clone lun as reported by the metahead.  You are correct, number of components can differ.  Just to mention it, even the expansion strategy (concatenate or striping) can differ between the two.  Simply wanted to bring this up as "Current Capacity" might not equal "Maximum Capacity" depending upon how you sized the additional space when expanding the lun.
Am I correct that the number of luns making up each metalun can be different between two metaluns that are being Snapview cloned? The metalun size is what matters.
