This is easy to explain. At first you ask that the whole button
bar has only one row:

  Rows 1

But then you specify buttons with a height of 3:

  (3x3, Container (Columns 3, Rows 3, Frame 2))
  (6x3, Frame 0, \
    Swallow(UseOld,NoClose) miniXMcd 'Exec exec xmcd -name miniXMcd')

Of course this does not fit into the button bar. Instead of
exiting with an error message, FvwmButtons calculates the total
number of sub buttons you need for all your elements:

  1x1 = 1 for the first container
  3x3 = 9 for the second container
  6x3 = 18 for the swallowed window
  ----------------------------------
        28 buttons total

To accomodate all buttons, it makes the button bar 1 button tall
and 28 buttons wide. This is why the button bar is so wide.

Finally, it places your buttons. The first container causes no
problem. The second one is too tall (3x3) and is cropped to 3x1.
The same happens for the swallowed window: 6x3 -> 6x1. You will
notice some error messages on your console:

  foo: Button too tall. Giving up
  Button=8 num_rows=3 bheight=3 h=1
  foo: Button too tall. Giving up
  Button=1 num_rows=1 bheight=3 h=0

So, in the end all your buttons use 1+3+6 = 10 sub buttons, but
the whole button bar has 28 sub buttons.

I recommend to use fixed geometries for the whole button bar
anyway. This way this funny button shuffling algorithm is never
used. At the end of the FvwmButtons man page you will find an
example (actually, this is my FvwmButtons config).
