Paul,
The purpose of 3-hole tape, as you said, is designed to be buried into the glue as long as the center row of holes are directly over the veneer seam and the tape does not overlap itself anywhere. The problem with using this tape is not about the tape but about veneer. Veneer is being cut so thin today that there is a risk in certain situation of ghosting under the right light and especially high gloss finishes. When veneer was a full 1/32" or thicker this was not so much a problem. Because of this I recommend using it only on the back side of a panel as this side is often never seen or only for a moment when a door is opened, not enough to be scrutinized.
2-hole tape is really designed for big industry where they sand their veneer tape off. The holes in the tape make the sanding process just a little easier. Since I dont sand my veneer tape but re-wet it instead I prefer the no-hole tape. I also find the no-hole just a little bit stronger when holding ornery joints together, and it comes off in one piece without falling apart like the two hole tape does. You do have to wet it two times to make it come off easily but with a little practice you'll get the hang of it.
This is a least my understand of the three tapes. There may be other explanations as well.
