Yup! And I reuse tubes when I wear out tires too. Honestly if you are ham fisted enough to screw up putting in a latex tube, you're likely to do the same thing with a butyl one
I think the point of the OP was to give his athlete a no brainier, minimum -risk set of instructions to install a latex tube ... acknowledging that he / she knows perfectly well how to do that, but wanting them to do it as correctly as possible to minimize the chance of a pinched tube. There's a big difference between 'follow the protocol' and 'don't be ham-handed!'
(Assuming Josh's video was the protocol in mind. But for fun, look at many of the other YouTube videos on changing a tube on a clincher, and you'll see that there are plenty that omit, for example, the step of partially inflating the tube after installing one bead ... to minimize the chance of pinching the tube.
