How does Google's Bunny Hopping Doodle Calculate Solution Length?

Today's doodle is about bunnies hopping on tiles, and writing code to get the bunny to every tile

I've done some testing on level 3 and found that loops, movement, and turning all count as 1 for solution length (loop, move, move, turn -> solution length 4)

Using that knowledge I went on to solve level 4, but the solution length does not match what I did

Is my way of calculating the solution length incorrect, or is Google wrong about the minimum solution length for level 4?

Also came across this issue on level 6
