this is Sozo saisei alone whithout byakugou
Hence she is doing a seal not automatically healing .

this black rod can not be touched .only characters like sasuke and naruto were able to after hogorumo gave them power YET Sakura was stabbed by it .not only a touch but it was inside of her .
Sakura wasn't effected by the rod even though it was inside of her ,because she was regenerating while it was inside of her . (byakugou :Sōzō Saisei is an automatic constant regeneration -by the databaook)
If she wasn't then she wouldn't be ok while it was inside of her
Madara see that and comment on it

He see the byakugou on her forehead but he mention she is using Sōzō Saise ( Sōzō Saisei is the regeneration tech of the byakugo because byakugo is not only regeneration and Sōzō Saisei is only one tech of it)
If she wasn't using Sōzō Saise(regenerating) he would say she used byakgou judging from looking at the byakugo marks . There is nothing suggest Sōzō Saisei unless she used it.
