[MCU] Loki. If Kang was trimming all other timelines then why were there such drastic differences between Lokis?

It seems anything even mildly different, it got pruned. So these Lokis were pruned from our own main timeline? Or is it mean he’s pruning other alternate timelines too? 

I’m guess I’m having trouble understanding, if there’s only one primary universe and timeline, where would variants as dramatic as these (alligator) come from? The old Loki says he lived in solitude for a long time and he was picked up the second he thought about coming back. So the TVA pruned him from a completely different timeline/universe?

TVA prunes universes that make Kangs, or Kangs that are going to be... problematic. 

There is a main timeline but they branch constantly, some of those branches are almost identical, some are very different.
