Can anyone explain what the difference is between a Multi-Tier and Multi-Layer architecture?
My understanding is that one is logical the other is physical.

Your understanding is correct. Now let us elaborate multi tier could be in different application domain means it crosses process boundry. Crossing process boundry does require serialization. My understanding for multi tier stays in same application domain, it can be physical divided in seperate assembly and not crossing process boundry. Multi tier serialization is required while multi layer it is not required.

Hope it will help you.
