The following pseudocode is executed using the "Shopping Bills" dataset. At the end of the execution, the variable `D` captures the following information: for each customer `Z`, `D[Z]["Shop"]` stores the shops visited by `Z`, and `D[Z]["Category"]` stores the categories of the items purchased by `Z`. But the pseudocode may have mistakes. Identify all such mistakes, if any.
```
D = {}
while (Pile 1 has more cards) {
Read the top card X in Pile 1
D = updateDictionary(D, X)
Move X to Pile 2
}
Procedure updateDictionary(D, Y)
if (not isKey(D, Y.CustomerName)) {
D[Y.CustomerName] = {"Shop": [], "Category": []}
}
D[Y.CustomerName]["Shop"][Y.ShopName] = True
foreach A in Y.ItemList {
D[Y.CustomerName]["Shop"][A.Category] = True
}
return (D)
End updateDictionary
```
