How one block transactions are created in bsc

I apologize if it is forbidden to ask questions not about Ethereum. I noticed that there are transactions in one block in bsc, they are similar to flashboot, but as I know there is no such technology in bsc. How do people create such transactions? In this case, as I understand it, a person put money on the address and withdrew tokens from it in one block, but when I try to create two transactions, I have to wait for the confirmation of the first one.

enter image description here

here is the address with these transactions – 0x1937C930BE3ACdf215F160b0E4619082202DA2C7

I also want to say that the sender of the first transaction is not a contract
