All lift also produces drag.

Due to the fact that the autoslat will only work if you have the slats extended I suspect that he got into the habit of extending the slats once he was below 250 KTS as an extra safety net. Approaching the stall I believe the auto slats will not work if the wing is clean. He is just trying to justify the early use of the slats. All lift produces some drag.
