It looks like those are Path Cookies.
Starting in v9.4.2 we sign Domain Cookies on a per-path basis. Domain Cookies belonging to the root path are signed in the main ASM cookie (TSxxxxxx, where the x's are generated from the HTTPClass name), and those belonging to sub paths are signed in additional ASM cookies with one cookie being added for each distinct paths.
Having said that, there seem to be three distinct ASM cookies in the above example, and I only see two paths.. there's only three if you count the trailing "/" which is on some cookies and not others, and I'm not sure if that 'should' be considered relevant in terms of distinct paths.
