Only true if there are the same number or more reserve days remaining that current month. Otherwise the PB days go in the bank and you can place them anywhere you want as long as there is coverage and without the other constraints of moving/dropping days.
So technicaly speaking, sometimes you can put them wherever you want. Its fairly common especially for days earned towards the end of the month where there is no place to put them that month.
