well, the main reason for this clause, or a clause similar to it, is to make
it clear that the license does _not_ require to have modified works be
licensed by the same license (as some licenses require) but instead that the
only requirement is that by using a different license you do not create a work
for that it is allowed to generate a work would be in violation of LPPL if it
would be directly generated from the original work.

yes that is the intent, though 7a is a pointer to 5a _in regard to the
original work_ thus even if you are the maintainer of your derived work this
does not mean that you, or somebody else is allowed to ignore 5a with respect
to the original work.

correct, explicitly applying 5a1 would be a simple form of an acceptable

well, as i said we would like to give the author of a derived work more
freedom what to do with his/her derived work, then, say, GPL does. For example
it would be ok to use a non-free license if he/she chooses to do so.
