I don't think it was accidental. I recall us discussing it, and agreeing that '50% black' sounded more like the description of a mid-tone gray than like a position. Especially to designers who had worked in print that used to spec screened colors that way. 

I also think it is easier to learn when the order is always the same. There is no confusion about whether it means something different when it is in a different position. We also don't allow the color stop list to come before the direction part, when in theory we could have.
