This is correct. Most people either start East or North. It doesn't matter but keep it in a fluid direction. Don't jump from North to South or East to West etc.
How clockwise/counter clockwise translates to casting is:
If you are starting facing East, you go East, South, West, North
If you are starting facing North, you go North, East, South, West
For Counter clockwise it is the opposite:
If you start facing East, it's East, North, West, South
If you start facing North, it's North, West, South, East
