Ah! Interesting. Thanks. Never used it before. SYNCH = "CALL with MODESET and Return as you were."
Usually SYNCH is used to call a problem state routine from a supervisor state routine (that's how we use it), but it can be a convenient way to restore state the other way as well. BAKR/PR can do something similar at much less CPU cost.
