untog didn't say that being successful and going to an Ivy League school are mutually inclusive. Untog said that attending an Ivy League school suggests the individual will be successful. This says nothing positive or negative about other schools.

Does mutually inclusive just mean the same? E.g. If A includes B and B includes A then A = B.

Mutually inclusive means: A implies B, therefor if A, then B.
