I'm positive. I have both tools and while the CT-3 does look strange with flat shallow splines it does engage perfectly. At first I thought it would be weak and possibly strip but I've used it multiple times with an impact gun to remove these freewheels.
The Park FR-4 is only 21.6mm in dia. and with 20-splines it doesn't come close to matching the 30mm dia./24-spline Maillard/CT-3 tool.
The confusion stems from the fact that older Atom/Maillard freewheels did use the smaller spline tool. For the freewheels supplied to Schwinn they changed to the large spline version (Model F2) in mid-'73. Below are pics of a '71 to mid-'73 vintage Model F and a '75+ vintage Model F3 freewheel. Both the F2 and F3 versions have the same large spline hole.
