It probably is. You've told the canvas "<Button-3> on any
item tagged with "P3" does this", and haven't rescinded that

In other words, the tag bindings are associated with the
canvas itself, not the individual items.

It sounds like you will indeed have to undo the tag
bindings explicitly.

Alternatively, come up with a tagging scheme that allows
you to re-use the same tags for the same bindings, instead
of inventing a new tag for each canvas item that you want
to bind an event to.
