If you decided based on actual evidence (ie. you looked at the paths, saw one was more worn, etc.) then I could understand that. The choice should have been meaningful.
But if you're going "Hmmm, I pick a direction at random, and I expect the GM to have decided what's in each direction already"
No.
The choice wasn't meaningful. You might as well have flipped a coin.
Meaningless choices shouldn't be put on that kind of pedestal, above the needs of GM, players, story, and gameplay.
I think RC was suggesting that in his example there were no meaningful choices because there really was no choice. Left or Right were really both Straight because the "fudging" taking place was of the railroady kind, rather than the die-shifting kind. Moreover, it seems his point is that if you place a lair in hex 8G, it's there whenever and however the PCs wander into that hex, even if they are short on resources and just hoping for a safe place to camp.
