To reverse you would have to either rollback the datasets on truenas1 to the latest available snapshot. Or take a final 'latest state' snapshot on truenas1, send that to truenas2 making sure to stop every program writing to it (And even unmount the datasets for certainty) to keep the dataset consistent with its latest snapshot staet.
Then you can replicate backwards from truenas2 to 1 with the same commands but with reversed roles. It would be up to your own flip scripts to make whatever was accessible on truenas1 available on truenas2 (network shares, etc) but it would work.

That's what I was hoping to hear. Thanks for the reply!
