Frost Wall + Empire's Grasp

Hi there.

First Question:
Is Frost Wall "push back" effect count as knockback?

Second question (if answer for question 1 is no):
If we using Frost Wall in Empire's Grasp gloves (reversed knockback effect + built-in knockback support) what will come first:
1) Push back
or
2) Knockback
?

BUMP, coz i dont have Empire's Grasp and can't test it.

Things in PoE tend to do (and be) exactly what they say, thus no, push =/= knockback

dunno but why is it that important? enemy cant pass through the wall and the wall damages enemies only once
