I reopened the question shortly after you voted to close it. I will add further explanation here in a few minutes, but there's another Meta post that I'm in the midst of writing that I want to address first.
Further explanation: On this question, 3 close votes were for "unclear what you're asking" and the other 2 were for custom off-topic, with the comment being
The OP does not seem to have understood the expression 'per se' in the first place."
I thought (1) it was abundntly clear what the OP was asking, i.e. whether or not those sentence used per se correctly, and (2) while the custom comment is factual, it is invalid as a close reason. The OP is essentially trying to ask if he/she is using the phrase correctly, which is inherently based on whether or not he/she understood the phrase in the first place.
Furthermore, it appeared that users may have voted to close the question because it was initially two questions. In that case, the appropriate close reason would have been "too broad".
In any case, I did not feel an argument was to be made for closing the question under any close reason.
