Visit data mismatch when using getPageUrls(), getItemsName()

I’ve got one question about the results that could be shown when using
Actions.getPageUrls() and Goals.getItemsName().

Currently, I’m tracking some eCommerce sites (which sells clothes) with matomo,
and recently found that the ‘visit’ data available with the ‘same product’ on getItemsName() and getPageUrls() doesn’t match.
( visit data from getItemsName() results bigger )

Is this behavior correct, by default?
