Just to clarify: The main My Account page doesn't show that. You have to click on View Recent Statements "Go" and look at the statements pop-up to see that. Then, scroll down to the Account Summary section, and at the right it breaks down into how many points expire each year (it'll only list years in which points will expire, so if you have no points expiring this year, it won't list 12/31/08, but if you have points you earned last year and points your earned this year it will list both 12/31/09 and 12/31/10).

Furthermore, it's complicated by the fact that you can't even "Go" to View Recent Statements for a quarter in which you don't have point earnings. So if you earned points last year but none so far this year, you may have to switch from Current Activity to the last period with activity to see this display. (Such a "no activity" quarter can happen either if you do nothing at Choice, or even if you stay a lot at Choice but only earn miles that quarter!)

OTOH, since you can see this for statements going back about a year and a half, by looking at old staements compared to the most recent one, you can see whether you had points that were going to expire that you've since burned!
