If you see videos online showing more moves, this is the reason. The videos are outdated because the video creators make them when the levels are first released. The studio monitors all levels when they are released and they check to see how many players clear a specific level and how long it takes for them to clear it. If it's too easy or too difficult they will "tweak" the levels a bit. The video creators can't keep up with the studio changes so you are still only seeing the first video release.
Here is a link to someone who is very good at writing tips so you might want to hold on to her link for future levels. The video might show more moves than what you have but she does mention that it was changed to 13 moves.
