Helping you with what you want

what I wanted, which is the 3-phases I've done before

Using Support Library 23.x+ you can do it modifying default BottomSheetBehavior adding one more stat with following steps:

1. Create a Java class and extend it from CoordinatorLayout.Behavior<V>
2. Copy paste code from default BottomSheetBehavior file to your new one.

3. Modify the method clampViewPositionVertical:
   

4. Add a new state

   public static final int STATE_ANCHOR_POINT = X;

5. Modify the next methods: onLayoutChild, onStopNestedScroll, BottomSheetBehavior<V> from(V view) and setState (optional)
   
   

So now you have those states:
STATE_HIDDEN
STATE_COLLAPSED
STATE_DRAGGING
STATE_ANCHOR_POINT
STATE_EXPANDED.

You can use setBottomSheetCallback like you do in original BottomSheetBehavior

The XML (without anything about parallax image like google maps) looks like:

<CoordinatorLayout>

    <FrameLayout/>

    <AppBarLayout>
        <CollapsingToolbarLayout>
            <Toolbar/>
        </CollapsingToolbarLayout >
    </AppBarLayout >

    <NestedScrollView>
        <LinearLayout/>
    </NestedScrollView>

</CoordinatorLayout >

I'm going to add a link to the example project where you can find what you are looking for

And here is how its looks like:
