Q different focal lengths for 1:1 image have same DOF?

I think I have this straight in my head from web searching but thought I would ask here too.

If I shoot a subject with macro lenses of different focal lengths at the focus distance where the reproduction is 1:1 the depth of field in both scenarios will effectively be the same? Is that right?

thanks

Peter
