Yes and no.

For non-intersecting clump members,it is done this way (see Clump.cpp
lines 179 - 190).

For intersecting clump member, it will be wrong, because masses are
considered multiple for intersecting parts.

Title:
  Loading clumps takes too much time

Status in Yet Another Dynamic Engine:
  In Progress

Bug description:
  The examples/packs/packs.py hangs in line 46 [1] because
  of appendClumped command.

  Changing it to "append" fixes the problem. So, it seems, 
  appendClump has infinite loop  somewhere.
