How will coroutine behaves when the promise is resolved multiple times and co-routine have next yield

For promise & co-routine, I've used bluebird npm package in NodeJs.

Can someone please help in understanding the behavior of below code when promise is getting resolved multiple times.

Question:

1. What will happens to coroutine when the promise resolved for multiple times?

2. Will the second yield will be affected by the multiple yield of first.

   const bluebird = require("bluebird");

   function func1() {
       return new bluebird((resolve, reject) => {
           let c = 0;
           SetInterval(() => {
               c++;
               let cc = c;
               console.log(`c=${c}`);
               resolve(true);
           }, 1000);
       });
   }
   
   let run1 = bluebird.coroutine(function*() {
       try {
           yield func1();
           yield func1();
           yield func1();
           yield func1();
       } catch (e) {
           console.dir(e);
       }
   });
