Except your clarification will be interpreted by a court of law. “This license is compatible with the GPL and I can interpret the GPL in a way that lets me do something this license says I can't” is much less likely to stand than “well maybe the author thought the GPL said this, but it actually says my interpretation”.

This, of course, presumes that such a license is actually compatible with the GPL, something I'm getting less and less certain of over time. (What constitutes a compiled form? If a predictive model doesn't count – which it might not, since it outputs source code, very much unlike how compiled programs normally work – then my argument falls down. And many other things would also knock the argument down; I'm not confident enough that all my assumptions are right, or that they should be right.)
