While you may be right to some extent, signature bears some information like stroke patterns, pen-holding and such, which are usually distinctively personal. Combine a few of these, and multiple of your signatures could probably be easily matched and verified even by a half-expert :) But as highlighted by other poster (maxbond): it's a commitment, and as long as you are not willing to challenge it, any of your signatures is sufficient to indicate intent.
