How far back on the ledger does MultiChain need to look up in order to determine that a user holds a particular asset when a transaction comes in?

It doesn't look back at all - it keeps a live database of unspent transaction outputs (also known as UTXOs), and can immediately check. Each transaction spends specific UTXOs rather than some general notion of a user's balance.
