My guess is that Radim was thinking of projection on the fly when handling
the proj info per vector map instead of globally as per raster.
Of course it is important to set things correctly.

in lib/vector/Vlib/header.c there is

Vect__read_head (struct Map_info *Map)
{
 ...
    Vect_set_zone ( Map, 0 );  
...
}

but Map->proj is never set AFAIK. However,
Vect_get_proj() is there.

Compare
../../../include/vect/dig_structs.h
-> struct dig_head
