Yup.  And, indeed, the same function has bitten us before:

  ;; We have to require this here to make sure that the following
  ;; dynamic binding isn't shadowed by autoloading.
  (require 'gnus-async)

Which I'd forgotten all about.  I've now required `gnus-art' as well.

I do wonder, though, whether this is a reasonable way for a Lisp to
work.  I think

(progn
  (let (var)
    ...
    (load "file-where-var-is-defvarred"))
  (boundp 'var))
=> nil

is somewhat wierd, although totally understandable.
