Why can't Blink be used again after putting it in a castsequence macro with Alter Time?

[Sideslash-ravencrest]

I wanted to make a simple castsequence macro using Blink and Alter Time, to be used in quick succession.

/castsequence reset=5 Blink, Alter Time, Alter Time, Blink

After using Alter Time’s second cast Blink does not become available in the macro.
Does this have to do with the GCD in any way? Or does Blink’s state change because of how it becomes available due to Alter Time and not by it’s normal cooldown?

It happens because both Alter Time spells have the same name but different IDs: start – 342245, end – 342247. So sequence waits until Alter Time cooldown resets. Is there any workaround? I don’t know.

Then why does it work with Displacement?

If you use /castsequence reset=5 Blink, Displacement, Blink
Blink is available, even if still waiting to recharge, but if using Alter Time it shows Alter Time’s cooldown instead if Blink’s cooldown, very strange.
