If one of the tanks dies, you get a raidwide AoE that can kill the other one, hypothetically causing a second AoE which would lead to the wipe. Et voilà, we have an healer check.
We already have plenty of healing check mechanics. They're just not often in the more casual end of content (eg white hole, photon+eternal darkness, charibdys, hellwind+towers, flare+stack, allagan field).
