Hi John, I can't answer for Dan so I'll just add my 2 cents here.
It is in my view safe enough to let a position expire i.e let all options that compose it "die" worthless if the market is at least 2SD, preferably 3SD from your nearest shorts. Of course your risk profile is personal and can differ from the mentor you are following so it is up to you to close your position earlier and avoid that risk particularly if there is virtually no Theta left in the trade. Alternatively, you can for instance place a conditional order triggered on a VIX level or a 2SD move of the underlying.
