When I got my second BP as a 3 month old she used to do something similar - right after handling she'd zoom around her enclosure. I was never sure if she was overheated or maybe overstimulated from handling. In any case they seem to be disoriented when they first go back in their bin, so what I do now when I put them back is (gently) direct their head right into one of the hides. Sometimes they come right back out but it seems to help them orientate - if I just plop them back in they tend to race around in confusion. I don't know how good their mental map of their enclosure is because they seem to be confused every time unless I show them the entrance right in front of their face.
