Intentionally, yes. I couldn't find a definitive translation that I liked. Here's another take:

"They [the Persians] are accustomed to deliberate on matters of the highest moment when warm with wine; but whatever they in this situation may determine is again proposed to them on the morrow, in their cooler moments, by the person in whose house they had before assembled. If at this time also it meet their approbation, it is executed; otherwise it is rejected. Whatever also they discuss when sober, is always a second time examined after they have been drinking."

I really just wanted to riff on the subject of involving alcohol in decision making.
