My spider ball Orion is like that. He's the most exploratory out of all of my snakes, but I have to watch him when I hold him for fear of dropping him on the floor because his grip is rather lax when he's on my wrist. He's a healthy snake, no problems ever, so maybe it is just a show of comfort.
Or maybe they're both wimps, and aren't that strong.
I don't think ANY snake is a wimp haha
