servicefactories accessed from componet factory in OSGI

Question

I am using component factory to create a multiple unique instances which in-turn uses services which is servicefactories to create multiple instance. My structure looks like TInterface - interface/service TInterfaceInline - which implements TInterface also consists of @Reference for another service.
Tinterfaceimpl1 - extends TInterfaceInline which is a servicefactory with filter property. TConsumer - component factory which consumes the TInterfaceInline by getting it in @Reference.

TConsumer

@Component(name = "TConsumer", factory = "TConsumer")
@Service
public class TConsumer implements IConsumer {

    // @Reference(bind = "bindInterface1", unbind = "unbindInterface1", target =
    // "(className=Interface)")
    // private Tinterface interface1;

    @Reference(referenceInterface = ParentProfile.class, bind = "bindInterface11", unbind = "unbindInterface11", target = "(className=interface1)", policy = ReferencePolicy.STATIC, cardinality = ReferenceCardinality.MANDATORY_UNARY)
    private ParentProfile interface11;

    @Activate
    public void activate(BundleContext aBundleContext) {
        System.out.println("Object = " + interface11);
    }

    protected void bindInterface11(ParentProfile interface11) {
        this.interface11 = interface11;
        System.out.println("ref object11 created");
    }

    protected void unbindInterface11(ParentProfile interface11) {
        interface11 = null;
    }

TinterfaceImpl

@Component(name = "TInterfaceImol")
@Service(serviceFactory = true,value=ParentProfile.class)
@Properties(value = { @Property(name = "className", value = "interface1") })
public class Tinterfaceimpl1 extends TinterfaceInline  {

    public Tinterfaceimpl1() {
        System.out.println("Generalprofile class : " + this);
    }
}

TinterfaceInline

@Component(name = "TinterfaceInline ")
@Service
public class TinterfaceInline implements java.io.Serializable, ParentProfile {
    // @Reference(bind = "bindtestin", unbind = "unbindtestin", cardinality =
    // ReferenceCardinality.MANDATORY_UNARY, policy = ReferencePolicy.STATIC)
    public Testint testin;

    protected synchronized void bindtestin(Testint inter) {
        this.testin = inter;
        System.out.println("Profile Class : binded parameterresolver " + testin);
    }

    protected synchronized void unbindtestin(Testint inter) {
        this.testin = inter;
    }

}

ParentClass

@Component(name = "PResolver")
@Service
public class ProfileClass implements Testint {
    public ProfileImpl() {
        System.out.println("Parameter class impl  : which extends ");
    }
}

Apart from this remaining things are marker interfaces. If i try to install in karaf , the state of the Tinterfaceimpl1 is REGISTERED. ie) i am using servicefactories and accessing service factories from component factory. Servicefactory class extends a class which implements Interface. What is the reason Tinterfaceimpl1 is REGISTERED.
