They are secured (SSL) and password protected connections. Any HTML formatted email will use the webkit engine to fetch and render the information via HTTP/HTTPS, and that will be the 64-bit engine underlying OSX.
Flash Player is entirely different. Although it appears to be running inside Safari, it is actually running as a separate process AND has access to your hardware. Your webcam, your audio input/output, user input (keyboard & mouse capture) and local file system are all open for Flash Player to meddle with, it is not the browser requesting these services, its the Flash Player process.
Flash Player can also read and write data to and from a user's file system independent of the browser process and can also trigger local executables. With click to flash enabled, I found that the download buttons on Adobe's website are actually flash buttons. When clicked, they start the Adobe download manager which resides on MY computers internal hard disk drive.
Flash Player as a 64-bit executable would at least give better protection in MacOS against code execution and hijacking. As a 32-bit executable, you might as well invite malicious code into your computer, serve it cocktails and give it a tour of your passwords.
