 In contrast to transferring an entire pool, if `obj` has a reference to `source->allocator`, it must be updated to `dest->allocator` manually.
 It is also possible to transfer registered memory from one pool to another, this way.
 
-The functions returns zero when the transfer was successful and non-zero if a necessary memory allocation was not possible,
-the `source` and `dest` pointers point to the same pool, or the pools have different type (simple, advanced, pure).
-In case of an error, no memory is transferred and both pools are in a valid state.
+The functions return zero when the transfer was successful, and non-zero under one of the following error conditions:
+- a necessary memory allocation was not possible
+- the `source` and `dest` pointers point to the same pool
+- the pools have a different type (simple, advanced, pure)
+- the pools have different base allocators (i.e. `cxDefaultAllocator` changed between creation of the pools)
+
+In case of an error, no memory is transferred and both pools remain unchanged and are in a valid state.
