Look at the questions again.

Can I use my Dec money to pay for a Dec ticket associated with a Jan activity. You will not need to slide anything. When you fill out your expense report it will ask you do you want this ticket in your Dec or Jan expense.

Yes, it is associated within 3 days of a valid FDX activity (your Jan R day). The bank money is not tied to a specific trip.
