Social Conversions Differing in Google Analytics Reports

[ryandiscord]

I'm trying to wrap my head around how conversions are reported between the Channels view (Source / Medium) and the Social Conversions report. I would have assumed that the social conversions report would show more revenue by including assisted conversions but that isn't the case.

Google says for the Source/Medium Report:

Includes only conversions where the traffic from a social network was the last click before the conversion, or conversions for direct traffic.

Am I right in thinking that a conversion path of facebook.com > direct with a 5 month period between clicks could report more revenue than the Social Conversions report because of it's 30 day lookback? If that is the case would the revenue be reported in the timeframe of the original click or for the new click?
