Yup. In HyperCard 1.x, the hilite state of buttons is constant across
all instantiations of that button, so background radio and checkbox
buttons show the behavior you describe.

This problem can be worked around by placing the button state in a hidden
background field, and using an openCard handler to set the buttons correctly
for that card. Some people have also used a font containing checkbox and
radio symbols, placing these in a field, instead of using buttons.

HyperCard 2.0 will allow you to set a property than makes the hilite
states card-specific.
