preserving AAdvantage miles

From http://www.aa.com/aa/i18nForward.do?...rogramDetails/
termsAndConditions/termsAndConditions.jsp:

"AAdvantage members must have mileage earning or redeeming activity
once every 18 months in order to retain their miles. Miles will first
expire under this 18-month policy on December 15, 2007. If your
account has no qualifying activity in any 18-month period, all miles
in the account will expire except for those miles earned prior to July
1, 1989 in accounts established prior to January 1, 1989 whose mileage
credit will not expire. Each qualifying activity extends the
expiration date of all unexpired mileage credit in your account for 18
months from the date of the qualifying activity. Qualifying activity
is defined as redeeming any AAdvantage award or accruing mileage
credit on any eligible American, American Eagle®, AmericanConnection®
or AAdvantage airline participant as well as accruing mileage credit
with participating hotels, car rental companies, credit cards,
telecommunication providers, and other service providers offering
AAdvantage mileage credit."

If I were to buy 1,000 miles from https://buy.points.com/AAdvantage/
index_buy.jsp, would that count as qualifying activity?
