Bathroom perimeter joints: just leave 1/4" open on perimeter if wood trim will hide?

Laticrete's TDS252 says the following:
"All installations require perimeter expansion joints. The minimum width for the perimeter joints is ¼” (6mm). If the perimeter will be covered with a shoe molding, then the joint can be left open to allow for the movement. If the joint will be exposed, then it should be treated with a suitable flexible sealant."

I want to be sure I understand correctly - as long as the 1/4" joint will be hidden by wood trim, I can just leave 1/4" open around the perimeter of my bathroom tile? I don't need to do anything more (obviously, I wouldn't grout this 1/4").
