To make sure you didn't do a straw purchase, and that you didn't sell them.
An FFL fills out a multiple purchase form only when you buy 2 or more handguns in a 5 day period. The exception is in the states bordering Mexico. In those border states the same applies in addition to 2 or more semi-auto rifles in a 5 day period.
I've never heard of the ATF visiting anyone who makes multiple purchases. They would need probable cause and a search warrant to do this anyways.
