I'm kinda new to playing the guitar and I found this video on youtube with tabs: 

I was able to learn and play to until the 2 minute mark on the song. But I'm having a hard time trying to 'replicate' the strumming sounds in the first few seconds after the 2 minute mark. According to the tabs, it has muted strings but I still can't make it sound like the one in the video. Is that just pure strumming? Cause it looks like he's barely touching the strings with his strumming hand (like during 2:04 of the video) and its like he's only hitting a few strings while he strums. 

Any tips would be appreciated. Sorry if the question seems stupid...
