That's not what a [typed value](https://www.w3.org/TR/json-ld11/#dfn-typed-value) is. Typed values are about DataTypes, rather than RDF classes. See also https://www.w3.org/TR/json-ld11/#typed-values

In essence that section of the spec says that a literal vlaue cannot be two distinct datatypes, e.g. both a dateTime and an integer.
