If someone withdraws their svXAI, the value of everyone else remains the same. This is because the total supply of svXAI will decrease in proportion to the XAI removed from the vault.

Conversely, if someone deposits svXAI then still everyones value remains the same because they are adding a proportional amount of XAI to the vault.

The value of your svXAI will increase as more XAI is added to the vault via the daily staking distribution.
