Does Yasuo equipped with Svellsongur trigger his 'When I attack' ability twice?

Ruling: Yes, Yasuo equipped with Svellsongur triggers his 'When I attack' ability twice when he attacks.

Sequence:

• Svellsongur copies Yasuo's printed text box
• Svellsongur grants that copied text back to Yasuo as equipment text (bottom bar)
• When Yasuo attacks, both instances of 'When I attack' trigger
• You can choose different targets for each trigger

Nuances:

• The equipment (Svellsongur) itself is not attacking; the equipped unit (Yasuo) is attacking
• Equipment cannot attack on their own
• Text on the bottom bar of equipment is granted to the attached unit
