See this discussion for differences between open source and hosted version:
The example you are showing does not include a turn restriction, you can try adding an intermediate stop and you will see that the result will be the same route you get locally, but with another estimated time of arrival.
If you want to try the effects of turn restrictions you do not need to build an index at all. Just disable speed or hybrid mode and you can still perform route calculations (they will just be much slower). And yes using hybrid mode would be a compromise between getting the full speed of Contraction Hierarchies and a faster index building time.
