i don't know how ZFS exactly allocates space, but i use gconcat with UFS 
and it isn't true.

UFS do "jump" between zones (called cyllinder group) when files are 
written to prevent unevenly filling them, so every zone always has some 
space to allocate.

The effect is that both drives gets quite evenly filled
