Hydelyn gave us a temporary power up after we fought her as a contingency plan (or, per Emet, possibly an apology), but her revival powers were only meant to be temporary. The fruit gummy using its own powers never gave anyone life, it just pulls people to us. Back in 5.3's fight against WoL!Elidibus we summoned Emet's soul and he used his own powers to drag us to safety before returning to the lifestream so living or dead doesn't seem to be as important as "Are they willing to help me?". If Hyth and Emet are not willing to help us, be it from memory wipe or curled up for the long sleep they deserve, that'd remove them from the summoning pool. Other dead friends that are conscious enough to respond would theoretically still be fair game.
