I don't know. A few years back I used to travel very frequently to both Armenia and Azerbaijan and had multiple-entry visas to both countries and countless Armenian stamps in my passport. I was never questioned at the Azeri border, never held up, no comment, nothing. I never heard from anyone who had such a problem.
It is, however, true that you will run into great difficulties in Azerbaijan if there is any evidence - in your passport or otherwise - that you have been to Nagorno-Karabakh.
