Semantics. For a given chainline, different cranks have their tapers in different places or for a given taper, different cranks have different chainlines. Same thing. I don't care. To place different cranks in the right place for chainline and to not hit chainstays and chains, different BB spindles are often required to get those two cranks to do the same thing.
