I have no idea what "post cloud world" means, but other than that, I agree with your assessment. There's a difference between "your phrasing screams that you are an outsider and you don't have a full understanding of what you are talking about" and "I truly do not comprehend what you mean."
I would be surprised if readers of this site honestly could not translate the buzz-filled marketing speak into what they actually are doing.
CMO: "we need something new, we have sold 'no software', we have sold 'cloud', we need something to sell to investors to keep this stock buzzing, after all we don't want the company to be valued on fundamentals, like Microsoft"
EVERYBODY IN THE ROOM LAUGHS
CMO: "I have a Forbes reporter coming in tomorrow, I need to give him something"
Marketing VP: "ok, how about 'post-cloud world'. it means that we are doing whatever is next"
CMO: "brilliant! a 'post-cloud world'. ok now who is getting lunch, i'm starving"
By him saying he's ready for the "post cloud world" shows that Salesforce is aware of the "buzz word" world we live in and that Salesforce is staying on the cutting edge.
It seems to me that they are interested in customer retention, being the go-to location for storing important business data, and that their business is much more concerned with having the best and most solid infrastructural, and they aren't simply creating a "cloud" for the sake of creating a "cloud". It's about what the "cloud" IS and what it's supposed to provide.
So, if the "cloud" isn't the best solution anymore, they will be ready for that.
As a former English-major nutjob, I do see some problems with how those sentences are constructed. The "internal activities and externally" is very awkward phrasing.
