Ever seen a spider gear shaft come out?

[Ledslinger]

I took the cover off my 1961 GMC 4WD Sub (Dana 44) off and the pin holding the cross shaft was hanging out. I imagine if the the roll pin comes out, the cross shaft comes out and wreaks havoc. Ever seen a diff that the pin came out? What did it do? Is this pin coming out, or is that what it should look like?

Maybe the cross pin can only go until it hits the inside of the ring gear, but then one of the spider gears would probably fall out.
