Ok, so maybe we aren't saying the same thing.
I think Soroka is in the rotation for the foreseeable future.
Even if there is a TOR starter added.
Rotation becomes Shota, Boyd, TOR, Soroka, Rea. (Horton gets a rest)
Then its Shota, Boyd, TOR, Taillon, Soroka (Horton builds back up)
Then it's Shota, TOR, Taillon, Horton, Soroka (Boyd gets innings limited. Assad to bullpen)
If there is no TOR guy added today, that puts Rea back in and delays hortons rest until Taillon and/or Assad return.
