Until USCIS has formally revoked the petition, another employer can file a cap-exempt petition for you. Once USCIS has revoked the petition, that petition cannot be used for cap-exempt purpose, but another can be.
For example, you have petitions through A and B, and USCIS revokes B’s petition based on consulate’s inputs. Thereafter, you cannot use B’s petition for cap-exempt petition through C, but can use A’s.
