You have just built the LogMiner dictionary and started the LogMiner session. You query V$LOGMNR_CONTENTS expecting to see the USERNAME and SESSION_INFO for some particular redo or undo operation.
However, the USERNAME field is NULL. This is NOT a recursive operation, and the USERNAME column is expected to contain a non-null value.
