I believe not? Both the 2p-ECDSA and Schnorr contingent payment schemes effectively encode "I will pay you N satoshi if you give me the private key of the public key P on the secp256k1 curve, before time B", which can be composed with another contingent payment of either 2p-ECDSA or Schnorr. So it would be possible to have a route with channels alternating between the two schemes.
Or do I misunderstand some detail?
