I am positive that was a goof. But as sci-fi fans are wizards at rationalizing.... Consider that the former involved Sinclair while the latter involved Sheridan. Two different kinds of leaders, somewhat similar, but still markedly different in personality and leading technique. Maybe Sinclair was more one to toe the line on such things and Sheridan more the type to bend the rules. Or possibly Sinclair DID bend them but we just didn't see it.
