Yes, a sensible behavior.

But there is still use-case for the radio-button like behaviour. Imagine
having a group with a series of orthoimages of different years and you
quickly want to see each year. In this case, the radio-button behaviour
would save you one click. So I don't think that this contradicts the
other proposal listed above here.
