Conference badges are often printed on-site by equipment owned by an event management company. So my guess would be that SalesForce wanted to get the badges to this group without them going through the standard conference registration process and so made them badges with supplies they had available to them - the official lanyards probably weren't ready yet (or were in the possession of the event management company) and they didn't own the thermal printers and stock used to make the official badges.
