L1A under Eb1 does petition title matter?


My husbands employer is filing for his GC .Currently they are evaluating his profile to see if he qualifies under EB1 category.My husband did work in a Managerial role for the same employer in India for 3 years and here in the US he has been working in a Managerial role for past 4 and a half years.My only question is his petition which was filed in 2009 the year we came in the US shows his title as a Project Leader which was good until 2012.Thereafter the petition which was filed again for extension of visa also shows him as a Project Leader.Though his title stating as a Project Manager is issued by his employer under the letter head of the company.

Does this still qualify him under EB1 category? If not what are the other options?

Please suggest!!
