<The sys.dm_xe_map_values, why it can see Reasons for Statement Recompilation>?

again: because of it is System sql server view that shows info based on the collected from last restart detail. It is how sql server works

Dynamic management views and functions return internal, implementation-specific state data. Their schemas and the data they return may change in future releases of SQL Server.
