I just tried that, and indeed using hildon_app_menu_add_filter() groups
the toggle buttons together into one row.

I made to screenshots to illustrate the point. The "radio group"
consists of the four buttons with the labels "Small", "Normal", "Large"
and "Huge".

1) Using hildon_app_menu_append() you get the normal 2 column layout:

2) Using hildon_app_menu_add_filter() puts all of them into the first
row of the menu:

I hope this helps! The drawback is, you can have only one Filter per
menu :/
