Leverage on Binance

Guys, I have a question about trading on leverage. On ByBit I have set the leverage x50 - 300usd x 50 = 15000usd the liquidation price is -2% and everything agrees because if the btc falls by 2% it must take my 300 to cover the loss. I have a problem with binance and insulated leverage x10 - 1000 usd x 10 = 10 000 usd. Similarly the liquidation price should be on -10% while binance shows me that the liquidation price is on -5%. WHY? After all, with a drop of -5% from my 1000usd, only half is lost, so why is it liquidating?
