talloc_tos in shadow_copy2_insert_string

I've been trying to figure out talloc best practise by digging through docs and existing VFS modules. One thing I can't figure out:
In vfs_shadow_copy2.c, function shadow_copy2_insert_string, the returned string hangs off a talloc_tos() context.
Doesn't this mean that the string will be deallocated before it gets back to the calling function, when the callee function's stack is destroyed?
This is what the code has:
return talloc_asprintf(talloc_tos(), "/%s/%s",
...and this is what I was expecting to see:
return talloc_asprintf(mem_ctx, "/%s/%s",
...since mem_ctx is passed to the function as an available talloc context (but never used).
What am I missing?
