[Samba] different shares use parts of the same path - is this allowed?

[lejeczek]

hi everyone

something like this:

[big]
path = /data/big
writeable = no

[my.big]
path = /data/big/my
writeable = yes

[your.big]
path = /data/big/your
writeable = yes

is such a configuration healthy? What are possible negative 
implications this may cause, if any?

many thanks,
