If you take extra damage from during an attack, then that doesn't trigger Jostero; the damage is still being dealt during the attack. If it's not during an attack (e.g. they hit an asteroid), then the extra damage would trigger Jostero.

However, at that point it's a bit odd to have waited so long, since the first damage that gave you Major Explosion would also have triggered Jostero. But that might damage them enough to convince you to use Jostero's once-per-turn ability on them instead of another target, since now you could finish them.
