With the update to the app on android, what does the restart icon with clapperboard and booster do?

There are two icons to restart the level, the one on the left looks like a refresh button.  The one on the right also has the refresh button with a clapperboard and a booster next to it.  When I selected it once it showed a commercial then restarted the level.  Is this an additional option to restart level with a booster if you watch the ad?

Yeah I've got that, the button on the left is the usual retry button whereas the one with the clapperboard gives you an opportunity to earn a pre-game booster by watching a video.
