You only have so much input resource production per second flowing down the assembly lines and its consumption is a distributed spread across all your processes that use it. Each production process eats into your limited resource economy and lessens the amount of available input elsewhere both energy and input wise.
If one process gets knocked out the others get a boost to resources. If enough of them get knocked out you stop consuming more than you produce input wise and it starts backing up. Thats at least one scenario.
One benefit of stacking a lot of train cargo with chest and four way equal divider splitter lines is that it creates a great input buffer for production. train cargo and chest feeding assembly lines filled with items are like item version of solar battery banks.
Its also what makes green arms so valuable for feeding assembly lines as they can uniquely stack a ton of items in one belt space especially with upgrade research
