I went through a match and watched every single person I used slowing hex on IMMEDIATLY use a movement ability.
Wraith? Teleport away using Project Mind
Grey Talon? Jumped in the air with Rain of Arrows
Mirage? Whirlwind away with Tornado
Shiv? Immediate Slice and Dice
I thought I had just used it wrong the first few times but then I paid attention to each 1v1 I was in and it NEVER silenced their movement abilities. They used them every time AFTER the Slowing Hex hit them.
