I facebook messaged the creator of the show Steve Weiss, here’s his reply:
Hi John,
there were 6 cameras (everyone had a cu cam, a dolly cam & a crane cam) and technically we never broke the 180 rule (not that I believe in rules) because when you cut to a dolly shot that is moving around the table wherever is stops you have just redrawn the 180 line from that point and that becomes your new reference.
I also recalled seeing a discussion about table shooting when I was reviewing Filmmaker-In-A-Box. So I messaged DP Jay Holben and sent me this blog article he wrote while shooting “2 Million Stupid Women”

Now this rule becomes complicated when you have more than two characters in the scene. If we sit four actors down at this table, we now have six individual 180-degree lines. Each time an actor looks at another actor, we have a new 180-degree line (also called “line of action”) as illustrated below (each line represents an eyeline).
He did first warn me that “it is an incredibly difficult situation.” so my confusion and concern doesn’t feel in vain.
I think the fact that my subject stays the same spatially, I’ll be “safe” – it’s not the standard semi circle arrangement that you see in all television… but it may be “okay”…
But I do want to throw out an example of “shooting in the round” which I thought was disastrous. I saw a Cirqu du Solei production on Bravo many years ago and the experience was so bad that it has stuck with me all this time.
This isn’t the worst case and luckily when the action gets going they stop jumping the line:
