Theres no point "saving" it if a wipe is imminent since LB bars gets reset upon death, asking you to use the LB is a last ditch effort to burst down the boss before they wipe...

I don't think that's always the case, because after wiping on Garuda HM we still had two bars full and I potentially could've used Starstorm to kick off the fight. The bars empty as soon as the primal gets pulled though.
