i know, his stats are not impressive at all and he has not been playing lately but...
i saw this video of him playing, i dont know if he has other linked accounts, coundnt find this one that he is playing in the video and seems like he does have other accounts.
watch the video at 0.25 speed and look at the bullets.
you can clearly see a 1 or 2 bullets increase after he shoots, this is not just in 1 video and i havent watched all of them, most of the ones that i saw he does the same thing.
