I watched the video on another site a couple of times. I suspect the butterrly had recently emerged from its chrysalis and wasn't completely ready to fly. They probably expected him to just sit there for their photo shoot. Once the butterflies start flying, they won't let you catch them and move them about very easily. I also don't think he would have stayed put on the koala's nose like that. But the koala was so cute about it - like she's trying to say, "Hey, look what I got. Look here. On my nose. Really, you gotta see this." So cute.
