In his explanation it was so that the fork code could be reused with no modifications. He implies it could be done if it matters to callers.
Now, I agree that this is a bit ugly in some of the details: in
particular, it means that if the system call blocks, we will literally
return as a *different* thread to user space. If you care, you shouldn't
use this interface, or come up with some way to make it work nicely (doing
it this way meant that I could just re-use all the clone/fork code as-is).
