Well, that's not very hard to understand. There is a single type parameter (declared with type variable E) which serves two roles, 1) constraints returned list elements type to any valid subclass of your base class, and 2) declares a type (using wildcard to allow subclasses) of Class objects being accepted by the method.

Whatever the actual type parameters are, they must match must that declaration, that's all.
