NFS and sub-mounted partitions

This doesn't seem to make sense:
I have an NFS export on my server 'venus://home/PICTURES' which works fine
and can be seen by other machines on the network. It got filled so I
mounted an unused partition below as venus://home/PICTURES/D70.

'df' on the server shows (among other thigs)
Filesystem Size Used Avail Use% Mounted on
/dev/ide/host2/bus0/target0/lun0/part5
9.5G 8.2G 1.3G 87% /home/PICTURES
/dev/ide/host2/bus0/target0/lun0/part6
18G 3.4M 18G 1% /home/PICTURES/D70
/dev/hdh5 18G 3.4M 18G 1% /home/PICTURES/D70

whilst 'df' on a client shows:

Filesystem Size Used Avail Use% Mounted on
192.168.0.104:/home/PICTURES
9.5G 8.2G 1.3G 87% /home/stolzy/PICTURES

'mount -rav' on the server shows:
mount: /dev/hde5 already mounted on /home/PICTURES
mount: /dev/hde6 already mounted on /home/PICTURES/D70

whilst 'mount -rav' on a client shows:
mount: 192.168.0.104:/home/PICTURES already mounted on /home/stolzy/PICTURES

Does this mean that I have to mount both shares individually (ie
venus://home/PICTURES as well as venus://home/PICTURES/D70) on the client?

Really? Surely if I mount an NFS share on my client it should show all
the sub-directories below it regardless of whether they are normal
directories or mounted partitions.

Are you saying that I have to mount the NFS share and then mount an NFS
shared partition below it? In fact I would be mounting one NFS share
below another, even though it was (on the server) itself mounted below the
same share.

The server looks like:
venus://home/PICTURES/D70

I want the client to look like:
home/PICTURES/D70

Are you saying I have to mount venus://home/PICTURES/ as
home/PICTURES/ and then mount the server
partition currently mounted as venus://home/PICTURES/D70 as
home/PICTURES/D70 below it?
