This makes the first preceding "@" unique to the twitter name. The leading "\b" is redundant and error prone since it is a word boundary marker character, but the at-sign is a word boundary character and so is sufficient. Removing the extra items in front of the group will pass the challenge:
contacts = re.search(r'''
(?P<email>[\w\d+]+@[\w.]+),\s
(?P<phone>\d{3}-\d{3}-\d{4})
''',string,re.X)
twitters = re.search(r'''
#^[,. \w\d@]+ # <-- commented out
(@[\w\d]+)$
''',string,re.X|re.M)
