web3.eth.accounts.create method doesn't actually create new account - ethereum

Question

I try to create an eth account via RPC in private network.
What I have done so far are:
launch geth node and create private network.
create simple javascript program using web3 1.0.0, typescript
run and get result as below but the account isn't created
Code:
const result = await web3.eth.personal.unlockAccount(senderId, senderPassword, duration)
if (result === true) {
// const newAccountResult = await web3.eth.personal.newAccount('password')
const newAccountResult = await web3.eth.accounts.create('user01')
console.log(newAccountResult)
}
Result:
web3.eth.accounts.create returns the following result
{ address: '0xf10105f862C1cB10550F4EeB38697308c7A290Fc',
privateKey: '0x5cba6b397fc8a96d006988388553ec17a000f7da9783d906979a2e1c482e7fcb',
signTransaction: [Function: signTransaction],
sign: [Function: sign],
encrypt: [Function: encrypt] }
But web3.eth.getAccounts method returns only 1 account.
[ '0xaf0034c41928Db81E570061c58c249f61CFF57f2' ]
Seems web3.eth.accounts.create method has succeeded as the result includes account address and private key.
But I don't understand why web3.eth.getAccounts method doesn't include the created account.
I also checked geth via console, the result is same.
> eth.accounts
["0xaf0034c41928db81e570061c58c249f61cff57f2"]
And eth.personal.newAccount didn't work.
Do I need to do something after web3.eth.accounts.create?
I appreciate any help.

If i got it right, web.eth.accounts.create is a way to create accounts without storing them on the local node, so its basically a way to get a valid keypair on-the-fly without storing anything on the keystore)
web3.eth.personal.newAccount() should be availabel if you have the personal-API activated on your geth node (which is default behavior for ganache, with geth you need to activate it via geth --dev/testnet --rpc --rpcapi eth,web3,personal (note: of course you should be very careful with allowing personal-API on mainnet, make sure that RPC access is restricted so only you/privileged users can access it)
(async () => {
let newAccount = await web3.eth.personal.newAccount();
console.log(newAccount);
let accounts = await web3.eth.getAccounts();
console.log(accounts);
})();
Should give something like
0xb71DCf0191E2B90efCD2638781DE40797895De66
