The key thing about it that is misleading is that a cast operator can only occur as part of a cast expression, and must therefore always be followed by either a unary-expression or another cast-expression (6.5.4p1). When occurring in a sizeof-expression, the parenthesized type name must NOT be followed by a unary- or cast-expression. If it were, it would be a syntax error (6.5.3p1).
