I do not think there is any visible positive effect in the big alts price yet, look at eth it has suffered the same path down just like btc so at the moment we see only one trend in the market and that is down.
Yes, I guess he said that while the bitcoin's status is negative the altcoin will going to benefit in that manner? If I am not mistaken I think most altcoins are dependent to bitcoin and bitcoin really influences the market value of altcoins.
