Does Cunning Action: Aim affect a Scout Rogue’s skirmisher ability?

I wanted to make sure my assumptions were correct that the Cunning Action: Aim would not affect a Scout Rogue’s Skirmisher ability.

As I understand, according to the Class Feature Variants UA

You can use this bonus action only if you haven’t moved during this turn, and after you use the bonus action, your speed is 0 until the end of the current turn.

and the skirmisher ability

Starting at 3rd level, you are difficult to pin down during a fight. You can move up to half your speed as a reaction when an enemy ends its turn within 5 feet of you. This movement doesn’t provoke opportunity attacks.

Because Skirmisher happens as a reaction at the end of an enemy’s turn the Rogue’s movement would no longer be 0 due to the Cunning Action: Aim. Is the assumption correct?
