"It won't affect people who have "Attack power rises while in combat" or any variation of that."

False

Tested in Titan's Cave

Buffs from others' passives / MLB Trystan with maxed Gladius normal hit / crit hit

None / 877 / 1277 Hero v2 / 957 / 1396

Frau / 917 / 1336 Frau and Hero v2 / 1001 / 1462

Phoena / 997 / 1456 Phoena and Hero v2 / 1089 / 1594

Frau and Phoena / 1043 / 1525 Frau, Phoena, and Hero v2 / 1139 / 1669

Clearly, Hero's passive can stack with other +attack passives: self-buffs (e.g. Trystan), auras (e.g. Frau), and subparty buffs (e.g. Phoena).

I'm pretty sure that the text in Hero's second passive refers to trying to stack two Heros' passives. I don't have one on my friends list handy to test that theory, though.

Using 0.1 * (base attack) * (buff1) * (buff2) * (buff3) * ... + (weapon attack) * 10 where (base attack) = 7600 (buff1) = Trystan's +5% attack passive = 1.05 (weapon attack) = 8

and the buffs (note in case you forget about order of operations: weapon attack is unaffected): Phoena (+15% attack) -> 1.15 Hero v1 (+10% attack) -> 1.1 Frau (+5% attack) -> 1.05 critical hits (50% extra damage) -> 1.5

Did the math for all of the numbers I posted above, and they line up with errors of no more than 1 point. In fact, if I truncated every single calculated number I got except for Trystan's normal hit with no buffs besides his self-buff, then those numbers would line up exactly with what I got in-game. (Dunno what's up with the 877 when I got 878 via calculations, but that's literally the only thing I can't truncate to get the same number, and it's a difference of exactly 1 point.)
