that's because cumulative mode will effectively make SRCDIR = "../src" "../src"
which will then expand to include("../src ../src/abc/def.pri") which is
obviously bogus.
the "combined parsing" daniel mentioned will solve the particular issue
that nothing is included at all, but it will miss the other possible
values of SCRDIR which are not in the current build configuration.
to make creator-friendly projects, try to avoid such clever constructs.
instead, make distinct complete include statementes which are executed
conditionally.

how did you determine that?
