I'm not sure what would happen if they did load it but I suspect they would be stuck on rope not going anywhere very quickly as it would compress the bars together.
Good Job
It doesn't go anywhere. Trust me. ;-)
Fortunately you generally make that particular mistake only once.
One other comment on the instructions, again applicable to the NCRC rules, but I'd recommend anyway.
After undoing the croll, take the hard lock off the rack, descend 1-2" to make sure there's no problems (like worse case scenario, you suicide rig the rack), then either soft-lock or simply stop, remove the upper ascender and continuing descending.
Taking this extra step becomes habit, but can help you catch a few mistakes that could potentially be fatal.
Overall though I want to say this is great. Teaching changeovers can always be a pain since often the person learning is 5' or more above your head, making hands on instruction tricky.
Thanks.
Oh and as for the tape, I'm guessing to ID it. I use red and purple tape myself.
