Kvoid Rabbonei Hakoillel Yichyu,
( Nidah daf 37A ) Here is the way you learn the tzad of Rava's Shaila of wether Koi'shi is soi'ser the zay'in Ni'Kiyim of a Zavah
"2. Or, perhaps only blood that is Gorem (makes her Teme'ah) is Soser; this blood is not Gorem (she was already Teme'ah)!"
This is not le'fi shitas rashi. Rashi learns because B'alma ( not by this specific woman ) Koi'shi is not Goirom a tumas Zivah and that is the way the Chidushei Ho'Re'Oh is also masbir Rashi. I am intrigued by your explanation, but would like a me'koir for it.
Thanks,

Lichvod Rav Kornfeld,
I agree that it is better to give Rashi's Pshat; we will fix the archives like below. My Peshat is like Tosfos ha'Rosh (at first we understand Gorem to mean to cause Tum'ah; this answers Rebbi's difficulty. Later, we understand that it is something that causes Zivah.)
The outline should read
(a) Question (Rava): Does blood seen b'Koshi Soser (cancel all) the clean days already counted after Zivah?
1. Tamei blood is Soser, and this blood is Tamei (she is still a Zavah);
2. Or, perhaps only blood that is Gorem (causes Tum'as Zivah ) is Soser. This blood is not Gorem!
Pesach
