From my understanding, and what I can read from what they said: They're suggesting Bitcoin is not practical for what the current average rate of transactions on other payment networks would require of it, should it even take on a lesser portion of those transactions (eg. X-thousand transactions per second). It is useful however for a value store. Eg. You can't rightly trade units of gold 50,000 times per second, but it's a good bet that if you buy some and stow it that it will at least hold or even appreciate in value.
