Ok,  I can confirm it works as expected.
I rebooted the VeID a couple of times and the changes in fstab are kept.

Even though, wouldn't be nice if there was a parameter to vzctl --bindmount_add
that could do like in virtuozzo.
I wouldn't be so difficult to create an script to replace the appropiate
fields in the /vz/private/veid/root/fstab and add it as a function in the
vzctl.
I'll gladly do the script if it was interestin.
