[diffeomorphism]

English only forces that if there is a definite article "the" (unique composer). If it instead said "a" composer, then it is impossible to answer "who composed" completely; you only know one of the composers.

Jumping to conclusions like "if A then B" to "A=B" is a very common mistake for humans, bad statistics and propaganda. So I am actually positively surprised that models don't make that mistake.
