No, he's saying for the two to be remotely competitive, it may be beneficial for a healer to have a slight lead over a tank in a perfect 100% uptime situation, given how much of their uptime will be wasted.

Apart from perhaps the recently overbuffed AST, tank-crushing healer parses involve virtually no healing; that's the only reason they're so ahead in any individual top-10 parse.

You'd be much better off looking at combined tank damage vs. combined healer damage, where you can more clearly see that the imbalance is nearer to some 200 dps in a perfectly healing-GCD-trimmed fight. That's enough for me to say tanks should probably have a bit more damage, but only a bit.
