RUD is very much a euphemism that has I guess drifted a bit from it's initialism; I'm pretty sure in this case the disassembly was planned and the survival case would have been unplanned.
I like reading Musk's tweets when he talks about something he knows (e.g. engineering). I don't much like them when they're ignorant and irresponsible commentary on Covid-19 (something he knows less about than even most ordinary but interested people, seeing as he wouldn't have the time to follow much expert commentary), or when he's sharing his puerile taste in humour or music or literature etc (although, to be fair, it's his personal account so he can share what he likes).
