Are you specifically talking floating-element or CRC lenses? I'd think the same level of attention to detail would hold for any lens (strict order and up/down orientation being followed). Is there something specific you meant by "side" of the element? I'd think that one would never willy-nilly flip an element regardless of it being an 18mm or a 50mm lens but wanted to understand if you meant something else.
