Mon and Dad quest in same acc with multiple chars?

i was talking with my friends about that new quest and one of them said,

"if you do the quest in same acc with multiple chars all Maple Points goes to acc?"

so here is the question cause i am curious about that too 0_o

The character that has the most of the NX cards will gain the NX.
any other character with less NX cards won't gain anything from it X:
