It just looks like there has been 0 care taken to do it. Like some kid has handed him a common card to sign and scrawled all over it. The boxes on sig cards are there for a reason the players should put in a bit of effort to stick to it for such a premium card.
That was my first impression too. Given the style of the signature it would have been tiny if he had tried to keep it within the box. I just wish I had all of them with the same number... but nevermind. I'm just happy to have them.
