Aspell does not use it directly.  It decompress it first.  A dictionary 
is created something like this:
  cat wordlist.cwl | word-list-compress d | aspell create master

In a read in one line at a time and then loaded into memory as the new 
dictionary is created.

Once a dictionary is created the compressed word-list is not used.
