Liquidity Pools is another dimension in this set of scenarios for Decentralized Exchanges. Basically it can be used in pair with or without bridges, so let's take a more clean example without them. But let's not stick to an Exchange Pair and work with multi-currency liquidity:

Trader -> Iroha: Register Exchange Liquidity [20XOR, 20ETH, 1BTC]
Seller -> Iroha: Place Exchange Order(1BTC, 20ETH)
Iroha -> "BTC bridge": Mint 1BTC to Seller
alt Success:
  Iroha -> Iroha: Transfer 1BTC from Seller to Trader
  alt Success:
    Iroha -> Iroha: Transfer 20ETH from Trader to Seller
  end
end

• Assets Transfer
• Iroha Triggers
