No, but you don't understand what the bounds are.

Right because the bounds of a node are calculated in it's
local coordinate system. When you set it's transform you change
the mapping of it's local coordinate system to other coordinate
systems, but you don't change it's size/location within it's local
coordinate system.
I think you want to use getTransformedBounds (probably
with the global transform of the parent of the node). Assuming
what you really want is the bounds of the graphics node in the
'global coordinate system'.
