Similar to Maria's answer, but not quite.
A Contradicting word
when printed in lower case, begins with a letter that has an ascender. b, d, f, h, k, l have ascenders. Though t breaks above the x-height line, it is not said to have an ascender.
Some fonts have a higher ascender height than cap height. So, what might appear contradictory about a Contradicting word, therefore, is that in some fonts it is taller in lower case than in upper case.
An Agreeable word
when printed in lower case, has no ascenders.
As BeastlyGerbil put it,
A Contradicting word is contradictory because the 'lower' case is actually taller than the 'upper' case.
Whereas agreeable words follow normal "uppercase is taller" standard.
The CSV version is unavailable because the font in the > has same height capitals
