it seems this vise has been added for the same reason to give more axes of movement.
Sorry, but I beg to differ – you don't get any more axes of movement at all with that arrangement unless you mount the x-y vice at some sort of rakish angle on the table. The saddle has x movement and the table itself has y movement, as is clear from the pictures. I have one of those x-y vices too, and I think that in terms of smooth x-y travel, I'd rather rely on the lathe, any day.
If you have to have some arrangement like that for workholding, you'd be better off employing a proper milling vice rather than that thing – you'd get a far more rigid mounting, and inevitably better results.

No I don't know what the horizontal boring machine above is, but the principle is the same as that of the Murad Bormilathe. The difference with the Bormilathe is that it also has a raiseable and lowerable tailstock, although aligning the whole lot is a bit of a pain… when I eventually get around to rebuilding mine, I will post pictures, because it's quite unusual.
