If it was supposed to be totally random and didnt work that way it would have become blatantly obvious throughout testing for a start, There's mentions in a few dev diaries/pre-release statements about them playing the raid (which should be obvious, since they would have had to do it anyway during the development process to make sure the mechanics work for the most part as intended and initially scale the difficulty up/down until they were happy with it). If the teleportations were supposed to be totally random it would have become blindingly obious to them at that point, since they would know exactly what's supposed to happen and how, and it would have been mentioned long before now. Also, the fact that it consistently teleports the furthest 3 people rather than just being the odd occasion it doesnt work (supposedly) as intended leads me to believe it was just a design flaw, not an actual bug. I'd also imagine the coding required to make it choose players at random and teleport them, as opposed to being dependant on range as it is at present would be totally different, they would have noticed or at least acknowledged it wasn't working LONG before now if it was actually a bug rather than an afterthought to try and increase the difficulty because they messed up. Also, regardless of that part of the encounter being a bug or not, it's not game breaking so they shouldn't waste time "fixing" it. It also doesn't change the fact that this is taking time away from making sure the next raid(s) work as intended and are foolproof so they dont fumble as badly as they did with this one. Maybe if they had a stickied forum thread/ help page of known bugs and the status of fixes for them (like most games do) they'd have far more credibility with their communit, rather than just keeping people in the dark and not acknowledging real issues while they roll out little fluff patches to shut people up in the meantime.
