on page 88 of The Edison Disc Phonograph . G Frow ( 1982 ), states that "from August 15th 1929 there would be no more direct mastering of diamond discs only needle cuts. in the New York studios unless instructed from West Orange".
Since production ended only 8 weeks later it does not leave a lot of time for the production of any lateral to vertical Diamond Disc dubs.
There is also a suggestion that a very few late blue amberols were dubbed from the laterals by R.Dethlefson.
Probably not an issue here, considering that the Roth recording was made in October 1928, but interesting nonetheless. Thanks for digging up the info!

...In my anecdotal observations, the take letters of the vertical Diamond Disc and the lateral needle-type are not necessarily the same take. That is, take "B" on Diamond Disc is not necessarily the same take as "B" on the needle-cut.
Apologies, drh. I was posting my reply at the same time as yours.
No problem--letters that cross in the mail, and all that. I've given the two records a simultaneous play test, and they are pretty certainly the same take--they stick together very closely once synched up. Human players aren't robots (modern drum machines are a different matter!), and even the most consistent of them will drift apart quickly in differing takes, at least in my experience. To be honest, I'd be surprised if more than one take of these records ever got issued; they were on the market for a matter of only a few months, and even leaving aside Edison's disastrous loss of market, I don't imagine the literature was such as to generate the sort of high demand that would call for replacing worn-out masters from one take with those from another, as had been the company's practice in its salad days.
[Edit] For whatever it's worth, I also looked the recording up in DAHR. It shows take B as the only one issued on diamond disc, and it states the following: "Recorded simultaneously as lateral 'Needle Type' master N-539." DAHR further indicates that only the one take of the lateral master was issued but that test pressings of two others are preserved at the Edison historical site.
