I dunno. The same splitting of things into concurrent events occured in the previous two films as well.
The opening of A New Hope is necessarily pretty linear, but once they’re on the Death Star and split up, the action jumps between Luke and Han rescuing Leia, 3PO and R2 staying hidden and supporting them from afar, and Obiwan sneaking around disabling the tractor beam.
The Empire Strikes Back pretty much opens with this same juggling, and it stays present the whole way through. First we’ve got the whole Luke-Lost-In-The-Wilds back and forth, and then when Hoth is attacked we jump back and forth between Luke and the other pilots fighting with Imperial Forces, and Han and Leia running around inside the base tending to last minute needs and then trying to escape. Once everyone is clear of Hoth, we’ve got Luke going off to seek out Yoda, we’ve got Han and Leia and company evading Imperial ships and ruthless bounty hunters, back to Luke training on Dagobah, then back to Han and Leia heading to Cloud City, et cetera
And all throughout, we’re constantly cutting away to see how the Imperials are holding up, to overhear their next nefarious move, to glean more information about the mysterious Darth Vader and his even more obscure master, The Emperor himself.
Splitting the action between concurrent events is the modus operandi of the entire series - the storytelling is structured like a novel, following several different but ultimately interconnected threads and jumping between them whenever is convenient.
