Is more of an indication as to how well he sees himself doing with his investments, it's not necessarily claiming to be the #1 holder.
Aka buying everything at 3.2, and saying still number 1, he's claiming that he finds value and does well as a result of it. The stock had tanked, he's mopping everything up and is proud to add to his portfolio at these levels as he thinks it'll take off from here in the midst of all this downramping.
Not to mention, he was never number 1 holder in 4CE so he couldn't "still" be number 1. But all in my opinion.
