I wouldn't say you're off base, but perhaps you're looking at it from a different angle than I think the producer originally intended?
Look at it this way - the Lightroom video tutorial came first, meaning a lot of people likely bought it.
To include the same info in Camera to Print as was included in the LR video would have been, for many customers, redundant, and from an editing standpoint, more work in creating the chapter markers etc.
Had the CTP video come first, with a sales pitch for a "video coming soon", I think it would have turned away some prospective buyers.
As for me? I purchased CTP first, and LR second, and would say that both items were well worth the money.
