IMO, the real semantics of the four attack buttons are:
T- high/up in general; F- cross wrists, hence the zwerchau from afar and duplieren when at the bind;
G- probably the most subtle and important button out of the four. If used at the bind, this is the winding button; if not, on first press, it brings your sword on line for a thrust, and on the second press, it inverts your grip for mordhau;
H- if used the first time, it does a cut; if used as a second attack in some combinations, it performs a follow-up thrust
The fact that zornhau-ort is "H-T" causes two problems:
- After I miss an oberhau, I press T somehow thinking that I will re-guard into ochs. Hell nawh, I do the "ort" in thin air. Re-guarding should not be a three-button sequence.
- Judging from how T-H and G-H work, my brain subconsciously thinks that "H on the second press is a follow-up thrust"... except it's H-T.
I get it, a zornhau-ort points UPwards, so you went with H-T, but considering how zornhau-ort is like hands and glove with the zornhau IRL and how H tends to get imprinted as the "follow-up thrust button", H-H would probably serve better.
The fact that switching back and forth between cutting and mordhau mode is NOT on a fifth button is probably THE source of the confusing key combinations.
- The contrived key combinations in mordhau. If you use a fifth button for mordhau mode, H becomes the overhead cross guard attack, and G becomes the "thrusting" attack with the pommel.
- The very fact that "initial thrust" is G, but "follow-up thrust" is H. After re-assigning "switch from/to mordhau mode" on the fifth button, it is now possible to let G be the "thrust" button in general, and H be the "cut if far away, wind if at the bind (you don't have zucken anyhow, which is probably just about the only cutting attack at the bind)" button. Then, stab, upper-stab and zornhau-ort would be "G-G (LOL aside, press G to keep thrusting! Note how intuitive this is)", "T-G" and "H-G" respectively, and go-around, winden and auswinden would be "G-H", "H-H" and "T-H" respectively.
