Why useMemo is used instead computed?

[cyevgeniy]

Taking the Button.tsx component, for example:

const showBorderRef = useMemo(() => {
      return (
        !props.quaternary
        && !props.tertiary
        && !props.secondary
        && !props.text
        && (!props.color || props.ghost || props.dashed)
        && props.bordered
      )
    })

or in Layout.tsx:

showSider: useMemo(() => {
        return !isMobileRef.value && !isTabletRef.value
})

Why useMemo is used here? Can't this be replaced with just computed?

Thanks!
I really thought that this issue was solved in vuejs/core#5912, but it seems that I was mistaken, because re-render still occurs even if computed is the same.
