You make it sound very complicated.
The OP is correct.
Any additional tax relief (ie the additional 20% for higher rate payers) either gets refunded to your bank account or HMRC adjust your tax code to take less tax off you over the next year (or two). This refunded portion does not get put into the pension resulting in > £40k, unless you specifically choose to put it in, & most people wouldn't.
