"Both the stateful and stateless session beans can implement multiple local and remote interfaces"

This statement is specified as a correct statement.
How is this correct?
As far as i have read , beans cannot have both the local and remote interfaces defined together.
Then how is this statement correct?
shouldn't it be like "....multiple local or remote ...."

Please correct me and clear my doubts..

A session bean can implement both local and remote interface(s) together.

From EJB 3 Core spec 4.6.6
A bean class is permitted to have more than one interface. If a bean class has more than one interface�excluding the interfaces listed below�any business interface of the bean class must be explicitly designated as a business interface of the bean by means of the Local or Remote annotation on the bean class or interface or in the deployment descriptor.

The following interfaces are excluded when determining whether the bean class has more than one interface: java.io.Serializable; java.io.Externalizable; any of the interfaces defined by the javax.ejb package.


From EJB 3 Oreilly - P no: 220
 
It is sorta covered in the JavaRanch Style Guide.
