Why didn't the one who chased them accuse them of taking back their money (as well)?

Rosh (to 44:9): Sometimes they would return a buyer's money, if they saw that the buyer needed it. 1

Refer to 44:1:1.1:1.

Presumably, the brothers did not lie about their wealth. Why would their money be returned? If the chaser was not the interpreter, we can say that he did not know that they were rich. Above (43:23), why did he attribute the return of their money to "Elokeichem"? It is because they did not know that their money was returned. (PF)
