If the profiles are configured that way. There is no method for including arbitrary commands into another profile (importing/copying aside), it's always the entire profile.
If the profiles aren't either in the list of the "Include commands from other profiles" or "Global Profiles" option, they're not "linked".
The "Include commands from other profiles" option is only one-way, as well. If profile A is the active profile, and it has profile B in its "Include commands from other profiles" list, that does not mean the commands from profile A would also be available in profile B while that is the active profile instead.
Only the profiles in the "Global Profiles" list are available regardless of which profile is active.
