I believe it means it locks the pool of 4* SRs and 5* SSRs down to the designated rate-up servants.

As for 3*s, none are on rate-up so you'd be pulling from the standard pool of many 3* servants. In the case of 4*s, the ONLY possible SRs you can roll from this specific rate-up gacha are Artoria Alter, Saberlot, Gawain, Tristan, Lancer Alter, and Berserkalot. For 5*s, the ONLY possible SSRs you can roll are Artoria, Lancer Artoria and Mordred, so it would be impossible to roll any other 4* or 5* outside of these servants on this banner.
