Dancers execute the given call until they have changed their facing direction by 90 degrees (1 wall). From that point they continue the execution of the call without changing their new (current) facing direction. If the dancers must change facing direction at any time in the process of the call, they end up facing exactly 90 degrees from their original facing direction.
