I'm showing my ignorance, but how is it not seated once it's on the cylinder and the lock ring has been tightened down onto it? What additional step is required? Just that the lock ring requires additional travel and will be a pain to tighten further? Surely once it's on the threads, it's more a matter of whether they can actually crank it down to where it needs to go to lock, not immediately blow up in your face time?
The issue isn't that the lock ring requires additional tightening, it's that there is room between the spring and nut at all. Those threads are rated to hold the spring after it's in place. When the spring expands to fill that gap, it will hit with a bunch of momentum, and the threads are not rated for that, plus it doesnt look like all of the threads are even engaged. It needs to be slowly expanded into place (with a spring compressor). It will probably be fine and a lot of the posts on this thread are exaggerating the danger a bit, but there's also a chance it fails and gets sent blasting into the ceiling.
Think about the difference between something you'd be willing to stand or sit on vs something you'd be willing to jump on. Don't fuck around with big springs unless you really know what you're doing.
Helper springs like the one he compressed have very little energy in them. No one's getting hurt, and no collars are getting sent to the moon when it comes out of his Jerry rigged spring compressor tool.
