There is a semantic difference between the pattern attribute and regexes as experienced by regular programming languages. Because inputs are clearly validating input, patterns default to matching the entire input string. However, normal regex engines usually assume you are searching for the string and matches any substring, though the details are confusing and vary between implementations. That means that unless you tell the engine to always match the entire string with your regular expression for emails, they will happily accept any garbage as long as it contains an email address somewhere in there. Since this would be a dangerous default, the semantics are to always match the entire input in patterns.
Consider our bartender in a hypothetical wristband-issuing club. When I show up at the door, I provide my ID and get a wristband that shows I’m over 21. The wristband “credential” carries “one bit” of information: namely, the fact that you’re older than some arbitrary age constant.

Let’s reuse the example of the electrical gate controller module. Assume there’s another module that for reporting purposes computes how much electrical power was used to open the gate. It takes the opening ratio, converts it to voltage and then uses some configured engine parameters to compute the power. In such a design, we would violate the High Cohesion pattern, because the knowledge about engine design and usage would be dispersed in two modules. If a developer had adjusted the voltage conversion logic, would he/she remember to adjust the second module as well? If not, a bug would be introduced.
