my sentence:
(1) He works hard so that he will be promoted.
Am I right that (1) has two meanings?:
(1a) He works hard in order that he will be promoted.
(1b) He works hard with the result that he will be promoted.
I backshift (1) but don't replace "will" with "would" to emphasize he hasn't been promoted yet:
(2) He worked hard so that he will be promoted.
Am I right that (2) has two meanings?:
(2a) He worked hard in order that he will be promoted.
(2b) He worked hard with the result that he will be promoted.
