Yes they actually recommend exactly that practice in the little care booklet that comes with new saddles.
Some leather treatments do indeed clog the pores and can ruin leather over a long period of time. Sno Seal is good stuff. It has a lot of bees wax in it, much like proofide. I used it on my hiking boots which were immersed in water daily on hiking trips.
