Not gonna lie,now you were really confusing me :D. But i think i’ve figured out, what you mean: you are talking about the damagetype, correct? Because in that sense you are right, the damagetype of an ailment depends on the damagetype of the inflicting hit.
I was talking about the damagevalue though, and in that regard basedamage and hitdamage are definitely not “the same thing” nor is the differentiation “just semantics”. On the contrary the difference has huge practical consequences.
What do the two terms mean?
“basedamage”: the damage of your skill without any scaling (passives, supportgems, auras, heralds, % increased damage taken modifiers etc) applied to it.
“hitdamage”: the damage that you do,when you actually hit a mob with your skill, with all the scaling included.
Let’s look at an example, in order to clarify the practical consequences:
Let’s say we are using a skillgem, let’s say Fireball, wich deals 100 base firedamage. If we ignite a mob with it, that ignite would deal 50% of basedamage as firedamage per second (50).
Now we can choose between various scaling options in our tree. We could pick up 100% increased spelldamage, 100% increased ignite damage or 50% increased firedamage.
The % spelldamge will not apply to the ignitedamage at all. We would deal 200 firedamage on hit, and still do 50 ignite damage per second with an ignite.
Likewise the % ignitedamage will not apply to the hitdamage at all. We would still deal 100 firedamage on hit, but our ignites now would deal 100 ignite damage per second.
Finally the % increased firedamage will work for both hitdamage and ignitedamage. (This is, what confuses many people, but it’s very simple: both the hit and the ignite are fire, hence % increased firedamage works for both.) Result for 50% inc. firedamage: 150 firedamage on hit and 75 ignite dmg per second.
Throughout this example the basedamage was always the same: 100 firedamage, whereas the hitdamage and the ignitedamage were always different, dependant on the scaling.
In fact the dot-scaling in PoE these days is quite similar to GD, where your Vitalitydamage and your Vitalitydecaydamage also are two completely different things.

Sry for that lengthy, slightly off-topic essay. I’m a nerd.
