Unexpected Co-Routine Behavior

Hello everyone, I was doing some work with coroutines and got a result I was not expecting. The critical parts of the script are below, but here is a summary:

Desired result: //script is doing things //coroutine suspends execution temporarily, shows debug message confirming it finished //script continues

Actual Result: //script is doing things //coroutine is called //script finishes execution //debug message from coroutine appears (so it waited, but did not stop the script while it did)

• realize I could put the rest of the code in the co-routine, but to keep things clean I'd rather just use the co-routine to stop the execution (which I thought it could do). Any ideas are appreciated.

     void MovePosition ()
       {
           if (nextPhase == false && inMotion == false)
           {
               transform.localPosition = Vector3.MoveTowards (transform.localPosition, endingPosition, movementSpeed * Time.deltaTime);
               if (Vector3.Distance(endingPosition, transform.localPosition) < 0.01f)
               {
                   inMotion = true;
                   if (inMotion == true)
                   {
                       StartCoroutine (WaitForRetract(rectractTimer));
                       nextPhase = true;
                       Debug.Log ("next pahse is " + nextPhase + " called from 1st block");
                       inMotion = false;
                       Debug.Log ("in motion is " + inMotion + " called from 1st block");
                   }
               }
           }
  
       IEnumerator WaitForRetract (float time)
       {
           yield return new WaitForSeconds (time);
           Debug.Log ("I finished waiting");
       }
