This inconsistency raise because the WebUI display author/tester email address but not the username of the user.
The XML-RPC's return user's username.
 
In [1]: s = nitrate.NitrateKerbXmlrpc('https://tcms.engineering.redhat.com/xmlrpc/').server
In [2]: s.TestCase.get(146417)['default_tester']
Out[2]: 'ebalintn'
In [3]: s.TestCase.get(146417)['author']
Out[3]: 'jscotka'

Check the https://tcms.engineering.redhat.com/accounts/ebalintn/profile/ this contains three field like "username", "name", "email".
Thanks.
