The "new law" is a provisional waiver of unlawful presence and it doesn't confer any new immigration benefits, but simply allows you to get a decision on whether a waiver has been granted before the immigrant leaves the US to interview. Because it seems like he has already left the US, this waiver will not help him because only those who are living in the US are eligible.

The standards for qualifying will still be high.

The provisional waiver program applies to persons living in the us. Your husband will have to submit a waiver after his immigrant visa appointment. The good news is that the processing times for these waivers should be the same (according to USCIS statements and estimates).
