I think they just forgot entirely the reason why it was assumed two timelines were formed in OoT because it was basically mandatory for that to happen thanks to time travel.
Adult world goes off on it's own to WW after OoT, that makes sense. Link went back to his childhood and did Majora's Mask.
Child timeline, that makes sense. After his OoT travels, Link puts away the master sword so the triforce isn't gotten by Ganondorf, something's probably done about him, and he runs off to find navi and Majora's Mask happens.
Past that, no real reason why a lot of them are connected overall, just a handful on why they make sense in like 2-3 game stints. Like, LttP and Link's Awakening make sense because LA Link's already been on adventures and is sailing about the world, and his dream world's heavily based on LttP bosses. Oracles games to LA make sense because he ends them specifically going out on a ship. Only goofy thing is LttP -> Oracles is a bit weird since it's like he doesn't even know Zelda.
