Yes, that's quite possible, but I can't find out explicitly how data was entered into that machine. Punched cards go back further (they originated from programmable jacquard looms), but you need quite a complex assembly to feed them in one by one, while paper tape just needs a few sprocket wheels to pull the tape along, so I think card feeders came about once machines were installed to be fed by secretaries in offices and computing undergraduates in universities, while the 1101 was designed by and used by the military.
That machine might actually have had one wheel too few, so he was probably tensioning the tape as it entered the machine.
Edit: Or more concisely, punched cards were an IBM thing. Everyone else stuck with paper tape.
