Unfortunatelly, the planes in ODE aren't planes; they are half-spaces.
Anything moving inside the half-space tends to be "ejected". So
multiply the whole plane equation by -1 to get a "plane facing the
other side" (i.e. negate the plane normal).

Congratulations, you were now chosen as a volunteer to update the Wiki
with this detail:

PS: OGRE got accepted for mentoring Google SOC, ODE could also become
one next time. At least someone to update all the docs.
