I'll take a stab at it (Chris or Chris or... may well ride in with a
better--or correct--answer):
It's fairly easy to look ahead lexically for a variable...once xxx has
become the name of a variable, it remains the name of that variable.
However, once a variable yyy contains a script object, it doesn't
necessarily remain a script object, and AppleScript can't (easily--or at
all in the presence of a run script) tell at compile time whether yyy will
refer to a script object at arbitrarily points in the code.
This is, roughly, the minimal example in which it doesn't remain a script
object:
script yyy
end script
set yyy to 5
display dialog yyy
--(displays 5)
--John
