The questioner has right and he has got a good question, which is still not be answered :-)

I tested this issue with a clean simple example. The fact is, that when the option 'do not keep activities' is checked, then activities will be killed. For example: A Mainactivity calls a subactivity. The mainactivity is killed. Pressing back on the subactivity results in restarting the Mainactivity. This can be a problem, when the mainactivity is doing longrunning stuffs like loading content.

My conclusion on this. The option 'do not keep activites' is an developer option and should not be set under normal user-conditions. So developer should be able to detect this setting.
