Yes, you are correct. The OSP is a temporary oxidation inhibitor.
You can paste the pads during smt process, this works quite well
and is a common practice.
It is done frequently on our designs and manufactring process.
If the boards is to be  wave soldered , that will cover the bottom side.
If the design is all thru hole , you may be better off with HASL or
you will need to get solder onto those pads needing to make good electrical
connection long term.
