Yes, exactly. So people need to allow a couple of extra days for the charges to POST, as opposed to the date they were charged. Meaning, if your statement close date is, say, Dec 15, don't wait until the 14th or 15th to make the charge and hope it reimburses in 2016. It won't.
A charge made so close to the statement closing date might well post after the statement closes, and be credited for 2017. Basically, unless you've got something you're waiting for, such as upcoming travel prior to the statement closing date, go ahead and top up your travel expenses now. There are lots of ways to "bank" that 2016 reimbursement, as seen in the Wiki above.
