No thermal-machine conclusion

Readout-and-drop equality does not determine heat, work, or reusable memory reset cost. For example, SWAP with a blank qubit gives the same reset channel for every common energy gap $\epsilon >0$, while transferring energy $\epsilon p$ for excitation probability $p$. The consumed blank and controls must be restored before a cyclic thermodynamic cost is asserted CheungEn07A. The present ledger contains channels and storage; it contains no specified thermal erasure machine.
