Digital Cockpit, different emergency brake warnings

[Sunsetter]

This is just a thread of curiosity, as I can't find any reference to the warning I got inside the digital cockpit.

Once in a while my front assist will randomly warn but never brake, accompanied by the warning sound and the below image:

I've had my car for quite a few years now and have only seen this light, except for today, where I instead got something similar to the below image. I've tried to recreate it:

Does this warning mean anything different? I can't find any reference for the image, and nothing in the manual specifies this warning.

Bottom one means :

• Red: This means the speed reduction set out by the automatic cruise control to maintain the distance from the vehicle in front is not sufficient. Reduce speed now.
• Green: Press the brake pedal to select a gear.
• Flashing green: The interlock button on the gear selector lever is not pressed.

So it has a special mode for when in cruise control? I've think I've been in cruise control all other times I've experienced the front assist warning light too.
