This is a total stab in the dark, but it's possible that they are using sufficient concentrations of this I3--->3I redox buffer to cause the lithium to react with it instead of the H2O when damaged. Of course I don't know what happens when that occurs either.

edit: here it is:

LiOH(aq) + HI(aq) → LiI(aq) + H2O(l)

So the existing I3 would probably use the free H+ to oxidize into 3HI before the Hydrogen could be released as H2. I think.
