Yup, this is correct. The search backends do sorting, and the Gnus
*Summary* buffers do sorting, but there would need to be some sort of
intermediate sorting process in the search code itself in order to make
limiting over multiple groups work the way you'd expect.

Maybe there's a simpler solution, but everything I can think of would
involve an awful lot of machinery just to make this case work the way
users would expect.
