Yes this is true. See a somewhat similar situation here although in his case he had a couple additional complications from taking too much leave/vacation time in the consular officers opinion.
It is not an absolute deal breaker however be prepared to explain why two weeks became two months, especially if you're a worker (two months is a lot of vacation for many countries) or a student whose school was not on vacation over that two month period.
Read this site on do's and don'ts and hidden requirements and problems like provenance of funds, funds parking etc to avoid making any of those mistakes.
