The out of the box transitions provided in our framework follow a specific pattern that exist on the Windows Phone device. They all have forward in/out and backward in/out transitions. In the case of the Tile transition we are animating a listbox, because this is the description of the transition by default. The element to delay is the clicked element and its relatives are animated just before that element.
If you want to animate different page elements you should take a look at the continuum transition - the ForwardIn transition specifically - it is again found in the sample code from the mentioned blog post.
If it do not suit your needs you can always create a custom transition based on oour framework. If you go on this option - please let us know if you need more questions.
All the best,
the Telerik team
