You're probably right. I haven't really thought about it that much, I'm just trying to articulate how I understand what I've heard.
I personally think that perhaps good ideas without execution have little value, but execution without good ideas probably has equally little value.
I say this because I've experienced cases where I had an idea that I thought was good, but did nothing about, only to (later) find somebody else who did the exact idea I had in exactly the way I would have. Clearly the idea had value for that person, but not for me - but the only difference is execution.
