Agreed, that is quite odd:

View "pg_catalog.pg_stat_all_tables"
Column | Type | Modifiers
------------------+--------------------------+-----------
relid | oid |
schemaname | name |
relname | name |
last_vacuum | timestamp with time zone |
last_autovacuum | timestamp with time zone |
last_analyze | timestamp with time zone |
last_autoanalyze | timestamp with time zone |
seq_scan | bigint |
seq_tup_read | bigint |
idx_scan | bigint |
idx_tup_fetch | bigint |
n_tup_ins | bigint |
n_tup_upd | bigint |
n_tup_del | bigint |

My only guess is it was done because the vacuum information more a
characteristic of the relation than the statistics. However, I agree
having them later makes more sense.
