Rotoscoping With Pen Tool

Hello Everyone.

I am using the Rotoscoping using the Pen Tool.

I have used the Pen Tool for many years with Photoshop,  Inside Photoshop when I Draw a path over a Selection, I use the Alt-key at the end of each path, to Draw more Paths.

I have noticed, when I use the Pen Tool In After Effects, for example If I am Drawing a path over an object and If I Alt Key on the  point of path It works different than Photoshop.

It Breaks the Path , rather than continuing the path.

Here Is the Screen-shot.

One Again Thank you very much..
