Markus,

It does save all of the samples that it's seen.  GNU Radio does not
process everything "instantaneously".  Since you're not causing the
graph to stop synchronously, say using gr.head, or by providing input
from a file, the graph is stopping at the first interruption point
that it comes to after seeing stop().  There are many threads
involved, and they are not all stopped atomically.

If you feed your graph from a file and let it run to the EOF, you
would get the same number of samples in all three files.
