Not exactly. He knew what would happen, but he couldn't write it. The best he could do was prune branches where the activities people did didn't diverge too much from his vision. All the heroes and villains chose to do what they did via free will. It was just that their free will was found to be acceptable.
True, but it's possible that that scene wouldn't have been part of that version. We can't know for sure.
Everything I’ve read online has said that Julia Louis-Dreyfus’ character was meant to be introduced in Black Widow, not Falcon etc.
That was strange. He got sent back BEFORE she killed He Who Remains, so Loki shouldn't have been in a different timeline.
That was a modified TemPad, and who knows what He Who Remains did to it?
Before she killed him, but not before the timeline started to branch furiously.
There still wouldn't have been any alternate timelines like that available. They get pruned. That timeline spawned from his death.
But he would have gone in whatever direction that timeline went. At worst, another timeline splits off and spawns another version of Loki in that timeline, but he would remain in the one he was in.
I thought the citadel was outside of time, so I assume that the portal Loki went back through could have been connected to any part of the timeline, including one of the new branches.
