Its because of packet utils
http://gnuradio.org/trac/browser/gnuradio/trunk/gnuradio-core/src/python/gnuradio/packet_utils.py#L104
I really hate the packet encoder/decoder, I am excited for this message
passing capability that gr blocks may get in the near future. We can
re-implement this packet framing stuff, and have a whole variety of them.

Looking at the GRC block "packet encoder" and the corresponding example
"grc/examples/simple/dpsk_loopback"
it is not clear to me why the "packet encoder" needs to have access to
the parameters "samples_per_symbol" and "bits_per_symbol".
My understanding is that the output of this block should be a stream of
bits (packed into bytes) that will then be used by an appropriate
modulator. The latter needs to know these two parameters, but NOT the
former.
