OK, ... does all this mean anyway?

First, some info:

My wife has had the Chase Visa account posting miles into MP and her last post was in Jan/Feb and she now has 35,555k. This is fine, btw, because someday she can use it to take a trip to Hawaii or something. (yeah, right. As IF there will be econ FF seats avail!)

Anyway, here below is her current balance and other info, and the text/format from the front page of how pretty much everyone's UA account looks online:

My mileage summary
Account summary
Account number: XXXXXXXXX
Membership level: Member
Current redeemable miles balance: 35,555
Year to date Elite Qualifying Miles (EQM) 0
Year to date Elite Qualifying Segments (EQS) 0
Lifetime United flight miles: 31,189
Redeemable miles expiration date: Jan 31, 2010

Please note that if your expiration date is after 12/31/07, your new expiration date will be 18 months after your last activity. Activity includes flying, redeeming miles, using your Mileage Plus Visa and more.

OK, so, if she does NOTHING with her UA account starting right now, then 18 months from right now (Feb 2007) is August 2008, right?

WHAT then, is "Redeemable miles expiration date: Jan 31, 2010???"
Is that like TOTALLY confusing to the layperson or what?

I mean WE here in FT know how to continuously check our accounts and calculate miles and activity within the accounts of loved ones and all, but ...!!!!!!

To me, it looks like they expire so far off she would not have to do anything until HAL predicts the coming of a second sun!
