Why is that?
it might possibly be related to hash randomization. I experienced a
similar "problem" during work some time ago, where I couldn't reliably
compare a set of values with a predefined list, without sorting it
first.
You can try the following Bash script to demonstrate the effects of hash
randomization in Python:
for _ in {1..5}; do python -c "print(set(['a', 'b', 'c']))"; done
Chances are high that you will get five completely differently sorted
sets.
Since Portage is programmed in Python, it might be the same effect here,
the packages are built up in a set or a dictionary and are therfore
affected by the random seed.
More information and pointers on this topic can be found in the Python
documentation: https://docs.python.org/3/using/cmdline.html#cmdoption-r
