I'm wondering why the entry 657 and 659 were missing. Isn't there any risk that
we reuse the entry and see mixed results in the UMA dashboard?

These were the original entries for 657 and 659, but it was accidentally dead
code and removed in https://codereview.chromium.org/928103002

I've tried to be clarify in the description about this.
