No, it's just a consequence of the way the color and graphics/ 
graphicx packages work (and a demonstration of the blunder made in  
pdfLaTeX when deciding not to set \pdfpagewidth and \pdfpageheight to  
\pagewidth and \pageheight, respectively, automatically).

Specifically, LaTeX by default is set for US Letter paper. Using the  
[a4paper] option changes this setting to A4 paper. However, this only  
affects \pageheight and \pagewidth. For pdfLaTeX, \pdfpageheight and  
\pdfpagewidth are set completely independently, in the file  
pdftexconfig.tex (namely, to A4 paper for you owing to the choice  
made when installing the TeX i-Package).

Now, the color, graphics and graphicx packages include some code to  
set \pdfpageheight and \pdfpagewidth to \pageheight and \pagewidth,  
respectively. The geometry package does the same.

Accordingly, here's what your tests should yield:

in)

independent, corresponds to the OS X Page Setup ("Format  
d'impression") setting

means more or less the same

means Page Setup set in OS X to A4

Hope this makes sense,
