The eggs in question are connected inside of one egg sac. Is this where two-headed/siamese tadpoles come from, or is there a chance they will split? Identical twins maybe? :D (I'm guessing not...)

I would imagine there may be different ways for it to start, but my Zaparos from years ago, used to throw a 2 headed tadpole every few batches. They looked like a normal egg to the naked eye until they began developing.

Very interesting, I would bet if they dont split it will be more likely conjoint twins over two headed. I have no clue but would love to see how it develops

Anybody ever seen a three headed tadpole? My Zapps threw one, once. It only lived about a week. That would have been too cool if it had morphed out into a three headed Zaparo! Of course, then there would be the concern of getting their tongues all tangled together when hunting the same fly! ;)

Ive had it when the eggs are conjoined but normaly one of the 2 dies and it all molds over
This is what ended up happening, they both molded over and the others hatched out. I'll update if another clutch like this is laid.

You can see an artist's rendition of a three headed toad here

I've had very similar eggs show up from time to time. For me, what looked to be 2 joined eggs turned out to be 2 eggs/embryos separated by a very thin membrane. The membrane became more visible as the eggs developed.

exactly. a 2 headed tadpole would start life as ONE egg which would split incompletely. of course this would happen early on in the egg's development, but i would imagine it would be rather apparent to the naked eye upon close examination. what you and the OP have are the frog equivalent of fraternal twins, where 2 separate eggs are produced together.
