If what the password is subject to, was encryption, and if that encryption was poorly done, then patterns in clear data could be seen in the encrypted output. However, properly done encryption does not have this problem, and, more importantly, passwords are hashed, not encrypted. Encryption uses a key and has an output size which is roughly proportional to the size of the input; hashing uses no key, and has a fixed output size.
Of course, repeating a password in a long sequence does not make it stronger; it just makes it longer. Password strength comes from randomness, not from length. A long password has more room for randomness (so it can help fitting more of it), but if you repeat the same string, then you are not putting any randomness in it, so the extra length comes to naught. You just made the password frustratingly harder to type.
Using the word "secure" in a password does not make it secure either -- quite the contrary, indeed, because "secure" and "password" are among the most common words used in passwords by unwary users (who certainly styled themselves as "witty").
