What happens if a character gets a second 2nd level aid spell cast on them?

@JeremyECrawford What happens if a character gets a second 2nd level aid spell cast on them, do they 'heal' 5 HP again and duration reset?

You can't benefit from the same spell at the same time. See "Combining Magical Effects" (PH, 205). #DnD https://t.co/AX2foEDiQ3
