Literally, that sentence identifies the action, but doesn’t say the reason.
The reason is stated in the sentance which follows:
??? ????? ???? ?????? ????? ?? ??????? ??????? ?????? ???”? ????? ???? ??? ??? ???? ??? ??????? ?????? ?”? ???”? ???? ?? ?????? ???? ?????? ????? ???????? ?????”? ????? ????? ???”?
Perhaps it would be sufficient to be mattir based on the ??? ???? of timers themselves, but that is not what he literally says.
My initial reaction to cherrybim was based on the way you’re reading it, but I changed my mind when looking more carefully.
If what you mean is that he would not have used that sevara on its own, but relied on it not to asser what was already done, I can agree to that. It would nicely explain his wording.
