[MW:23644] ASME B31.3_2014- 341.3.3

Dear Sirs

341.3.3 Defective Components and Workmanship
341.3.4 Progressive Sampling for Examination.
When required spot or random examination reveals a defect, then
(a) two additional samples of the same kind (if welded or bonded joints, by the same welder, bonder, or operator) from the original designated lot shall be
given the same type of examination
What does it exactly means by stating " two additional samples of the same kind"

My understanding is
1- Can be 2 additional joints-100% NDT( same type of examination )    OR
2- 2 additional  films on another joint welded by same welder/operatot.

Pls advise
Thanks
