this means that \u always matches uppercase characters regardless of whether ignorecase is set or not. \c is (at least in this case) equivalent to setting ignorecase before search -- \u still matches only uppercase letters. Because \C is used to make a pattern independent of the current value of ignorecase, \u does not change when used with \C either. > And when you look up > > :help /character-class > > it shows you what's considered a character class.

As such it behaves differently depending on the current value of ignorecase. If set [A-Z] matches lowercase letters, too, as is the case when \c is included in the search pattern.
