In general, joins in file geodatabases perform best when they are one-to-many or one-to-one. This is the sole query optimization logic used when you're using file geodatabase data with this tool. However, if this would result in querying Table2 on a nonindexed field, and reversing the order would result in querying Table1 on an indexed field, the order will be reversed in an attempt to maximize performance. For example, if Table1 is listed before Table2, Table2 will be joined by getting a row from Table1, then getting matching rows from Table2. When input tables are from a file geodatabase, tables generally join in the order listed in the Input Tables parameter.
