Has my 'cluster' operation succeeded?

I ran this command:
cluster verbose address using address_locality_lookup;
And got this result:
INFO: clustering "dba.address" using sequential scan and sort
INFO: "address": found 0 removable, 29323623 nonremovable row versions in 1139047 pages
DETAIL: 0 dead row versions cannot be removed yet.
CPU 26.00s/8286.70u sec elapsed 8342.01 sec.
CLUSTER
Time: 9366585.421 ms
Does that indicate that clustering succeeded (ie all the rows are now in the order indicated by the address_locality_lookup
index)?
What do 'removable', and 'nonremovable' indicate?
