But before San षन्, only stu स्तु and /Ni get /Satvam after the /abhyAsa.

The word San षन् means "a /san that has turned into San षन् by << Adezapraty...". So this rule is an exception to << Adezapraty.... It forbids siSi सिषि suSu सुषु in —

/sic' + /san → !**sisikSa- सिसिक्षॱ

sU सू + /san → !**susUSa- सुसूषॱ

because /san changed into Sa ष, so there is already enough Sa ष-ness there.

However, if the /san stays /san, << Adezapraty... works as usual —

**tiSThAsa- तिष्ठासॱ

And with stu स्तु —

stu स्तु + /san + /tip → **tuSTUSa तुष्टूष + /tip → !**tuSTUSati तुष्टूषति

The /Ni in the sUtra means Sa-roots with /Ni added, such as sevi सेवि —

(sev सेव् + /Ni) + /san
→ sevi सेवि + /san
→ sevi सेवि + iSan इषन् by ArdhadhAtuk...
→ seve सेवे + iSan इषन् by gbS
→ se से + seve सेवे + iSan इषन् by sanyaGoH
→ si सि + seve सेवे + iSan इषन्
→ si सि + Seve षेवे + iSan इषन् by this rule
→ !**siSevayiSa- सिषेवयिषॱ "wants to make (him) serve"
