<div>
without understanding the PNG file format, which they both would have a header, which is probably the same size no matter what size the image is, <br />
<br />
and then im guess the difference is in how the compression is working.<br />
it may handle the larger blank space in the x2 image better as there is a lot more of the transparent section<br />
<br />
i;m not too sure, but this is a guess

In Illustrator, I've saved for web on the 2x image.  I then save for web and change the dimensions to 1/2 the size.  The 1/2 size image is actually larger.  How is that possible?

Why is smaller image larger?

Illustration software is distinguished from photo-editing software in that the result is an original construction, rather than the manipulation of a photograph. Illustration software uses vector-based tools such that the content is stored digitally as resolution-independent mathematical formulae describing lines (open paths), shapes (closed paths), and color fills, strokes or gradients. Vector paths are constructed of anchor points and path segments. Illustration tools typically create precise lines, shapes and patterns with well-defined edges and are superb for working with complex constructions such as maps and typography.

Adobe Creative Suite (CS) is a software suite of graphic design, video editing, and web development applications developed by Adobe Systems. Each edition consists several Adobe applications, including Photoshop, Acrobat, InDesign, Premiere Pro or After Effects. Photoshop, InDesign, and Illustrator are the industry standard applications for many graphic design positions. CS6 is the last version of the Creative Suite; future versions of their creative software would only be available via their Adobe Creative Cloud subscription service.
