Yes

It was a very important game for Ahri, she knew that if she wanted to finally escape gold and be promoted to platinum she had to do everything in her power to win. She was playing very calm and focused, waiting for the right time to strike. She knew that the enemy jungler was Evelynn a demon-like creature that could easily charm and overwhelm her and that's why our heroine bought a vision ward.

After 2 more minutes spent in the lane, fighting off Yasuo and playing careful Ahri spotted that Evelynn wanted to gank her from the lower, river bush. She had a vision ward there, so the invisible succubus had no chance of assasinating her. Our heroine just simply used her ult to escape the danger.
