Bellagio Ruling Question

[Xelent]

An interesting situation came up when I was playing the 2/5 NL at the Bellagio last night. The rules of the game are that you have to buyin for $200 and you can buy another $200 if you go under $100. I was at about $95, so I took 2 black chips from my pocket and put them on the table inbetween hands.

The next hand, I raised preflop and on the flop. Another player looked at my seemingly small stack (no, I wasn't hiding the blacks, they were on top of my reds) and said "I put you all in," and put a stack of about $125 out. I explained to him that I had him covered and showed him my black chips. He said he couldn't see them and he took his money and said "Ok, then I raise you $50 more." Because I didn't care and was going to muck anyway, I didn't say anything, but what is the ruling in that situation? Does he have to be all in?
