Hi David,
Sorry to be blunt here, but no it doesn't make sense - and I also think it is incorrect...
Websites do internal 301 redirects all the time (redirecting from old page to new page within the same site) BUT your explanation above appears to say that OSE does not follow those redirects and move the data from old to new url ? That would make for a pretty useless SEO program...
Your message also appears to say that if we have to go contact everybody that links to www.mysite.com/old-page.html and have them change their link to www.mysite.com/new-page.html ? That's just silly...
I think your explanation is incorrect because SOME of the 301 re-directs I have done on my site have passed the data perfectly in OSE and Moz. Run OSE on these two URLs and you will see: Old URL = www.bestdryingrack.com/clothes_drying_rack.html New URL it was 301'ed to = www.bestdryingrack.com/clothes-drying-rack-main.html
So it appears that inconsistency is the a big problem here. That should be some firm rule like: "Moz will transfer all data across 301 redirects on the same domain within 1 month" This would let us analyze or sites without trying to keep track of silly situations of which new pages have the proper data and which ones we still need to fudge between old and new page data.
I hope this all makes sense...
