Blitzcrank rocket grab not grabbing furthermost away

So my Pyke was hitting the enemy Kennen as only their Blitzcrank and Kennen were left with my Draven and Pyke being the only ones left on my team. Blitzcrank had just pulled in my Draven so that meant Pyke was furthermost away yet my Draven got rocket grabbed again then knocked up causing me to lose as both Draven and Pyke died to the Kennen ultimate.
