mount command behaviour

[bobafetthotmail <starshipeleven@hotmail.it>]

Hi, I was porting in Jessie a script that worked in wheezy,

it does the following:

-mount --bind "$folderX" "$folderY"
-mount -t tmpfs "scriptname" "$folderX"
-cp -rfp "$folderY/." -T "$folderX/."

It seems that now when mount the folder X as tmpfs (the second step),
also the bindmount is mounted as tmpfs.
So the last step fails saying that both are the same folder.

if I write "mount" I get (pasting only the relevant parts):

/dev/sda2 on /var/scriptname/home/username/testfolder type ext4 
(rw,relatime,errors=remount-ro,data=ordered)
scriptname on /home/username/testfolder type tmpfs (rw,relatime)
scriptname on /var/scriptname/home/username/testfolder type tmpfs 
(rw,relatime)

The first line is the bind mount, the other two lines are generated 
after I do the mount to tmpfs.

And both /home/username/testfolder and 
/var/scriptname/home/username/testfolder (its bind mount)

are mounted as tmpfs.

Is it a mount bug or was I using a bug that was fixed?
