It's a computational mode in the camera. It takes an initial photo, and then a series of photos of equal length, and composites any new light on the subsequent photos on the first. In this case, from memory, it's 5 photos at one second exposure each.

Basically, it lets you do a long exposure, without blowing out static light sources.

There's a slight post processing change to the colour, to bring out the orange/teal effect, but it's pretty subtle

That sounds really interesting, thank you for explaining. The last firework I tried to capture was horrible, just as you described, the static light sources blew out. Does this technique have a name I can look up? Maybe my camera has this function as well and I haven't found it yet.

And thanks for the tip with my language settings, I tried to adjust them.

On my OM1 Mkii it's called live composite mode
