Although I do love triathlons and have been doing it for 3 years now I am nowhere near an expert. To put things in perspective, my last olympic triathlon I finished in 3 hours and 3 minutes which was exactly 60 minutes behind the #1 finisher and I was HAPPY

That time put me in the top 30% of my age category believe it or not. Both the cycling and running had a lot of vertical so it was fairly brutal, I was very happy to finish the 10k run and feel good at the finish line.
Having exposed my level of in-expertise, I would worry that doing back to back olympic length triathlons two weeks apart is asking for injury - unless you will be treating them as just training exercises and not going all out.
What if you skipped the July 1st triathlon and instead did a half marathon a few weeks later?
