One scapula slower than the other?

Hello I saw this video and took a video of my own back while doing the movements like in the video and found out that my scapula behaves almost like his. It moves a bit slower than the other.

 

Is this something I have to worry about? I was lifting weights for 2 years and started gymnastic training since last week including scapula strength etc.

 

This is the video:

Don't worry, there are 99.99% chances that you are perfectly normal and in good operating state.

If you pay attention to how you feel while exercising, a lot of this will clear up as you move through F1, but you'll need to follow the program exactly. Don't skip any iM sets, etc.
