Android Navigation component deeplink backstack

I am doing navigation component codelab. In 10 part we add deeplink widget.

I replace destination to R.id.flow_step_two_dest

  val custAtgs = FlowStepFragmentArgs(2)
    val pendingIntent = NavDeepLinkBuilder(context)
        .setGraph(R.navigation.mobile_navigation)
        .setDestination(R.id.flow_step_two_dest)
        .setArguments(custAtgs.toBundle())
        .createPendingIntent()

And have this graph

enter image description here

It works. After press back it is returned to home, but I expect that it will return to Step One.

Is it right behavior? Or am I doing something wrong?

It is the intended behavior.

This is from step 10 :

The backstack is generated using the destinations specified with app:startDestination. In this app we only have one activity and one level of navigation, so the backstack will take you to the home_dest destination.

Pressing the back button should take you back to home_dest.

More complicated navigation can include nested navigation graphs. The app:startDestination at each level of the nested graphs determines the backstack.

Wrap flow_step_one_dest and flow_step_two_dest into a nested graph and set flow_step_one_dest as the start destination.

Pressing the back button should take you back to flow_step_one_dest then home_dest.
