I guess that is the line of reasoning. If they tell the losties about their discoveries then someone is bound to ask what they were doing out in the jungle. And so one lie becomes a web, so they just thought it was easier to say nothing.

This is kinda shaky though cause why not just say they were exploring the island. Seems like that would be simple enough.

I hope that we find out that Paulo or Nikki or both were in contact with the others via the walkie talkie and their reasons for keeping secrets are because of the others manipulation.
