I don't expect that another instance should change behavior. Looking at the internals of String::Random, perl's built-in rand is what is used for randomness.

From perldoc:

rand() is not cryptographically secure. You should not rely on it in security-sensitive situations. As of this writing, a number of third-party CPAN modules offer random number generators intended by their authors to be cryptographically secure, including: Math::Random::Secure, Math::Random::MT::Perl, and Math::TrulyRandom.

This is maybe something the OP should take note of.
