I'm in doubt as to whether I correctly identified this as a malformed
SWF. Adobe's SWF specification states that integers should be
zero-padded as needed. With charity, one could extend this notion to
'integers' taking zero bits: fill the remaining bits (i.e., all of them)
with zeros, and the resulting integer is zero.

So the situation above could be taken as legitimately calling moveTo(0,
0). I suppose a test could show whether this is what the pp does, but
not whether this is in-spec.
