Look at it this way, if your healer can heal you 3k less in the first phase, that's not going to save them a heal at all. You'll just possibly enter the next phase with 3k more hp. Unless you can preserve this "gain" throughout the entire fight by never overwriting it with overheals on the tank it's very unlikely that you'll be able to save a heal gcd.
This is my logic. Regardless of whether DH > Tenacity or the other way around, healers are overhealing most of the time so the extra damage reduction isn't going to have that much of an impact. In theory it's nice, sure, but between overhealing and +/-5% damage/healing variation it just seems so negligible either way.
