You are quite correct!

I have no idea why people get so confused by this.  Factoring in the crop factor, lenses of equal maximum aperture will produce the same framing and exposure across systems.  Only depth of field will differ.  Thus the lenses are equivalent in one respect and not equivalent in another.
