Yes, that's how hierarchy is specified in verilog.

A module instance with its port names and numbers is the connection
data to another schematic, or chunk of verilog code.  If a verilog buss connects
to multiple instances called out as the same module with instance numbers like 
[7:0]
the same schematic or chunk of verilog code will be used 8 times in creating 
the circuit.

But gschem has no way of executing that specification at present with names in 
verilog format.
The names have to be unique and create a flat netlist is the way gschem does 
pseudo hierarchy now.

It would be nice to have a netlist that used modules and instances and the 
subschematic was existing only
once and when you changed it, all the instances would update.
