State history range doesn't change

[s1na]

I am trying out the path-based archive mode. I have a snap-synced mainnet node which was at the tip of the chain. I stopped it and first added just the --gcmode=archive flag, it indexed 90k blocks and I could query the last 90k states indeed.

I stopped the node once more and added --history.state=1000000 to extend the index range. It doesn't do any additional indexing. It said:

INFO [10-02|12:40:45.387] Enabled state history indexing
INFO [10-02|12:40:45.387] Initialized path database                triecache=614.00MiB statecache=409.00MiB buffer=256.00MiB state-history="last 1000000 blocks" index-history=true journal-dir=/home/ubuntu/datadir-geth/
geth/triedb
INFO [10-02|12:40:45.387] State histories have been fully indexed  last=5,369,269

But this was immediately on startup and I'm sure the node didn't do any work to index between 90k and 1m. Also trying out the API I don't see those states as available.

history.state specifies the number of available states to retain.

Since it's a snap-synced mainnet node without 1,000,000 available states, it will retain
all currently available states and prune the older ones once the number exceeds the
1,000,000 threshold.

Right, confusion started for me because at first when I enabled it with just 90k, it went back and indexed the last 90k blocks. How did that work?
