In Daemon hunter, under the section of Slaanesh Herald Gifts, the Gift Scion of the Serpent grants Step aside and Swift attack talents.

Seeing as all Heralds have swift attack is this to be ignored or is it a typo and should say "Step Aside and Lightning Attack"?

If anyone knows or have made your own ruling any info would be apreciated.

noticed it to. i believed you guess right but can't confirm sorry

The Gift says it grants those talents to "All Slaneshi daemons who can see the Herald of Slanesh...". So they listed it because nearby lesser Daemons would not already have swift attack.
