That shows it can be done at least. Maybe, instead of pulling and overlapping like we often see in demonstrations, a person could tuck the fabric underneath every alternative pull. In other words, you could pull-tuck-pull-tuck. Each pull would meet edge to edge, and each tuck would meet edge to edge. As I'm envisioning this, proper box pleats would be created. Let me test this on a small scale and I'll post pictures if it works.
