There is a little more than those 6 "primary reference clocks" 
contributing to TAI/UTC. Checking with Circular T and associated data I 
found much more clocks, even a R&S Rubidium clock contributing a little. 
There is also hydrogen clocks that contribute.

So, the article isn't completely correct.

The lower uncertainty of the NPL clock is found in that material.
