I do not have that exact light, but I have bother their D25c and D25a. The way the UI works is that the strobes are accessed on the second pass after turning on and then every other pass afterward and always after high. So for your example of turning on at Med: M/H/ML/L/M/H/strobe sequence/ML/L/{repeat from beginning}.
I have the D25LC2 MkII "clicky"
In head loose mode my light goes Moon- Low- Medium- High- Moon- Low- Medium- High-Flashythings then back round again.....
In head tight mode it toggles beteen Turbo and Strobe.
In head loose mode you can program the torch to start on any one of the brightness levels you like and it will start the rotation from that point in the above listed sequence.
It also has a configurable level of brightness on the moon and low modes.
I thought I'd like it but I'd prefer it had a forward switch, the reverse switch just doesn't suit me. I did temporarily swap on the forward switch from another of my eagletac lights and I liked the way it worked (ie you choose your brighness mode before you do the full click).
The torch is VERY slim line, way slimmer than any of my other 18650 Eagletac torches. It looks and feels very well made and has a good clip.
That said, I bought it but I don't use it, mostly because of the switch but also because I've found others tthat suit me better.
