It's been a long time since I looked at the tutorials, but I don't think you know where the golems are placed until you start it.
This is correct. Once the scenario is loaded though, you can use the stylus to tap on the map tiles and confirm the positions of the golems. On a regular scenario, there would be a deployment phase between beginning the scenario and the first round. However, because there is no deployment required in tutorials, that step is skipped.
