it looks that he transferred this amount to another wallet as there is a second "red arrow" transaction, isn't it?
"mark coins" has no idea what he is talking about. Your best option is to simply ignore anything he says. He is participating in a signature advertising campaign, and he gets paid for creating posts, therefore he will say any sort of nonsense just to get a post into a thread.
"shorena" is also participating in a signature advertising campaign, but he has clearly taken the time to learn about how bitcoin works and seems to be interested in actually helping people. He has many helpful posts in this forum and generally gives accurate advice.
As mentioned by shorena, there is no way to know if your friend "transferred this amount to another wallet" unless you know for certain what wallet he is using.
If your friend is using wallet software that gives him control of the private keys (such as Electrum, MultiBit, Bitcoin Core, blockchain.info, etc), then yes he transferred the amount.
If your friend has an account at a bitcoin service (such as Coinbase, Localbitcoins, etc), then he doesn't have control of the actual bitcoins. The service may have transferred the amount in order to consolidate funds, and may have failed to update your friends account for some reason.
