I think the problem is with the interfaces such as Steemit who stubbornly assume that 1 SBD = 1 USD.
If you want to know the actual USD amounts, chech out your posts on SteemWorld.
I very much agree with you that these complications suck. Back when SBD was worth several USD, the dollar amounts you see on Steemit were off by a wide margin, too, but the other way. Now that it's worth 60 cents, you get the author rewards in USD by dividing the figure by two and multiplying it with 0.6, which is completely stupid. But I guess there are more pressing concerns right now than correcting that.
