The only reason he doesn't Sending Arazni, when Sending Iomedae fails, is that he forms an intention to do so if three coins come up heads, which ought to be just as visible to Her and saves him the good wand most of the time.
(Much later when he learns why this would have been catastrophic, he does a quiet internal retrospective on what policies he should have adopted that would more definitely save him from aggravating the enslaved corpse of an ally he believed to be alive.
He can't think of any, not really.
He's slightly pleased with himself that he bounded the cost of Iomedae averting that catastrophe to 'modify a coin flip', until the quickly-following realization that he cannot trust Her.)
He Sendings Iomedae, which fails, and probabalistically Sendings Arazni, which fails, and then catches sight of a patrol riding towards him, and has the wands away before anyone with fewer decades than he has on the front stands a chance of noticing them.
