On a regular shabbas the teffilah of retzei vhachlitzainu in shmoneh esri has three variations:
In maariv it is בה .
In shachris and musaf it is בו.
In mincha it is בם.
There is a reason for this difference (gematria or a parable of a bride).
My question is, when Yom Kippur falls on shabbas, my machzor uses בו in neilah. Is there a reason for this (other than the editors forgot to differentiate)? Shouldn't it say בם since it is after mincha?
