Moving media between blogs changes the URL subdirectory

On wordpress.com, I'm exporting media from one blog and import it into another.

Problem: On the source blog, some media files are e.g. in Folder "2014/02", but they get imported into folder "2014/03". As a consequence, all links in posts to this particular file are lost and need to be re-edited.

The cause seems to be that some media files have been uploaded in "February 2014", but they were published in "March 2014"

In the export XML file, you can clearly see that the original file was located in 2014/02/1.png. But since the publication date was in March 2014, it is getting imported into 2014/03/1.png, which is another directory.

Is there a way to import media files with the original URL location ?

Here is an example export of one of such media files:
