Recipes says eggs, not egg whites, so it would be whole eggs.

In the instructions, does it say to separate the egg yolk from the white for the sponge step?

Whole eggs as,stated in the recipe

I think the author intended whole eggs. The sponge has to hold up against pretty substancial richness. But it might be interesting to try just egg whites. I'm not enough of a baker to be sure of making changes that effect the texture.
