For this non-standard team comp, can someone explain the E N1 E N2 at the end here? I would understand E N2 if they want "swap to mualani and do two charged bites with her skill," but the notation here confuses me. Swap to Mualani, okay, press E, okay, hit with a charged normal attack, okay... press E again to end the skill early ???, then do two normal attacks outside of the skill (???)

What purpose does this serve?
