How Nested test execute in parallalization in Cypress

Question

if I have nested describes

describe('Desc1', () => {
  describe('Desc1.1', () => {
   });
  describe('Desc1.2', () => {
   });
});

then when I run it in parallelization is the Desc1, Desc 1.1, and Desc 1.2 will be distributed to machines or will they executes in the same machine

just wanted to check if it's going to save some time or not in case of nested test suits
