Attacks are distinct actions from each other and happen in sequence. After you blink, the foe should consider your new position and decide what to do next. You may or may not be able to attack that foe again. Knockback works exactly the same.

Note that Blink is in no way a retreat — it does not help again further attacks if these can reach you. There is no mention of retreating, and no reason why retreating rules allowing further attacks would apply.

All that said, Blink makes you lose your turn unless you buy up an off-attribute Hard skill that serves no other purpose. It’s pretty good defensively, but I wouldn’t use it most of the time unless I was faced with some steep Dodge penalty.

Blink (and Phase) should protect from both strikes when defending from a Dual-Weapon Attack, as these are simultaneous.
