H1B Visa RFE Question

I have filed my H1B from company A and company B also filed my H1B. Now I got company A’s petition got approved and got RFE on company B’s H1B. Company B has answered my RFE and they have withdrawn my petition before a final decision was made by USCIS. I have got my stamping done on company A’s H1B.

Could you let me know what are the consequences that my both H1B gets revoked.

B’s petition can never be used in future as it was revoked even before it was approved.

A’s petition can be used for future cap-exempt petition filing even after the same has been withdrawn by the employer.
