It's actually the lack of -g option miscalculating dependencies depending on 
how you look at it.

With the -g option, emerge ignores the USE flags that you have specified in 
make.conf and uses those that each binary was built with for that package. 
Hence, the binaries don't bring in the new packages listed above.

Without the -g option, emerge will calculate the dependency tree based on your 
current USE flags and what is in /usr/portage regardless of the USE flags 
that installed packages were built with.

To confirm what I'm saying, try 'USE="-*" emerge -gepv world' and you will see 
that any binary packages used will not have all USE flags disabled.
