How could this guy bid if he has a negative budget?

What is this with the negative budget? See some guy buying couple of players with a budget of -400M.

I remember I could not bid if my budget was below the asking price of the player...

FCB explained it in his post. At the time of bidding as long as you have enough money originally for one player, then you can still bid on multiple players, if you win them all then you go into the negative

But I saw him bidding like 5 hours earlier also with a negative budget...well strange
