For instance, A salesman can work to sell mobile phones directly for a company , like NOKIA. or he may work for an independent sales agency, which is under contract with the company LG, which makes some of the phones that NOKIA uses.
The last sentence, which makes some of the phones that NOKIA use, is strange here, if it modifies the company LG, The logic is unreasonable, LG makes some of the phones NOKIA uses? They are two different companies, Please; if it modifies the sentence that he may work for an independent sales agency, also no logic here is. Could someone tell me what the meaning is? or it's just a confusing description of salesman.
