Hedging

Sir, in the BPP study text, under Matching receipts and payments, it is stated that a co. offsets its payments against its receipts in the foreign currency, and that it does not matter whether the currency strengthens or weakens against the co.’s domestic currency because there will be no purchase/sale of the currency. So I don’t understand how both the income and expense are left at risk. A foreign currency account was also suggested under matching.
Netting in the book is defined as a process in which debit and credit balances are netted off and that its objective is to save transaction costs by netting off interco. balances before arranging payment. So is netting more of an intra-group/ related-party sort of thing?
I would be really pleased if you could clarify the above. I got all confused reading the study text.
Thanks in advance.
P.S. I pasted this here from the comment section in the foreign exchange risk video. Figured you might not come across it there. You are always of immense help. Thanks again.
