what does 70% after deductible mean?

In the plan that I'm looking at, it says "$30 copay for 3 visits, then plan pays 70% after deductible". Does that mean that I will have to pay the full doctor's office price for visit 4+ until I have paid all of my deductible -- then after I have paid all of my deductible of say $3000, then the insurance company will pay 70% of doctor visit costs?
