Given code "move left, move left, move left," what happens if you change it to "move left, move left"?

📘 Worked solution
✓The character now ends 2 steps left instead of 3 - one fewer move.

And one from the hard end

The code "move right, move right, move right, move right, move right, move left, move left" was meant to move a character exactly 3 steps right with no leftover movement, but has a mistake. Identify the error and correct the code.
