All of the other different colorbled parallel sets have print runs with specific designations. Doing a little Google search, somebody online suggested this was a back door product which was accidentally released in packs and not supposed to be released.  
Can anybody further expand regarding this set? Were they 1/1? Should they be listed here? Should they have the "SAM" or "PROMO" designation since they seem to be sample cards? 

Only what's on BCP. I don't think anything needs to be changed for now.

How can a backdoored (stolen) product be released in packs?

Speculation is the parallel was intended to possibly be a SN1 (but was never stamped), something happened and they weren't added to packs early in production, some may have been added later on, and the rest were likely backdoored after the bankruptcy.
