When the Instinct of the Event Card ask me to draw some GS, I need to draw from the Left Blip or from the Swarm of GS?

I played the Swarm of GS, and I lost as very soon.

Draw from the side that the genestealer is appearing on. So for example if it asks you to place a GS behind a marine who is facing right, draw from the left pile.

Thank you the answare.
