Yep! I figured that out after I posted this. Since that was the only new text that was added to the document after export. Also I tried the method mentioned in the article link above but it did not work for me. I could still see all the fonts in PDF. I know printers need not do this but a lot of them still do and the ones I work with offers me very competitive rates and timelines. Its a tradeoff I guess. Thanks for all your inputs folks. It really helped.
