So far, that's pretty much what I said.

Not according to ASLG, but maybe you have a better source:

"Initializing Script Objects

"When you define a script object, you define a collection of handlers and
properties. When you run a script containing a script object definition,
AppleScript creates a script object with the properties and handlers
listed in the definition. This is called initializing a script object. A
script object must be initialized before it can respond to commands.

"If you include a script object definition at the top level of a script
‹ that is, as part of the script¹s Run handler ‹ AppleScript initializes
the script object each time the script¹s Run handler is executed. For
more information, see ³Run Handlers² (page 303).

"Similarly, if you include a script definition in another handler within
a script, AppleScript initializes a script object each time the handler
is called."

Agreed.
