String Binding to Alarm Pipeline

I've tried to bind the Alarm Pipeline properties of an alarm directly to a string parameter property.

I know I've got the correct string because I double checked by creating a "normal" binding, directly to the alarm pipeline that I want the alarm the enter.

Can anybody confirm that this does/does not work?

Seems like it does not work.

Using a memory tag:

Manually toggling it into the alarm state and use the binding on the Alarm Pipeline I get nothing in the alarm pipeline.

Changing the Alarm Pipeline to be static and toggling it into the alarm state I get the alarm in the alarm pipeline.

Edit: just did it again, and it seemed to work. Maybe this has to do with when exactly the alarm enters the pipeline. I restored this from a backup and the tag has been in alarm since the start of the gateway. Maybe it needs to see that initial trigger for it to enter the pipeline.
