Everything in froc happens on a "timeline". When you bind a changeable
value, there's a chunk of the timeline that corresponds to the dynamic
scope of the bind function. When the value changes, that chunk is
removed, which unregisters any dependencies created in the course of
evaluating the bind function.

So it is true that dependencies created outside a bind are not
removed; but you can always fix this by wrapping everything in a
top-level bind (as in the code I posted).

Best regards,
