   Right.

   SI-second = second   
      
   (Very loosely:)   
   At the geoid a 'UTC-second' = 1 second   
   In GPS orbit a 'UTC-second' = 1.00000000044647 second.   
      
   You are  confused because you don't know what coordinate time is.   
      
   See in the paper above:   
   1.2 What is coordinate time?   
   1.2.2 Coordinated Universal Time (UTC)

   All facts are irrefutable.
