I mean: It is difficult to say "A UID comment refers to the mainkey" or "A UID
comment refers to the subkey" (and make sense). A user ID is simply a string
describing some person or other entity. If the comment is "CEO of Example
Inc." how should that be related to the mainkey other than to a subkey?
There are other situations: I use (abuse?) an additional user ID to make
statements about both mainkey and subkeys (by stating that the mainkey is
offline and how secure the subkeys are).

For several reasons. A notation is a subpacket (i.e. some additional
information) to a signature (self-signature in this case). The UID comment ist
just text between round brackets.
Self signatures are used to bind both user IDs and subkeys (and some other
stuff) to a mainkey.
You can have a comment in the user ID and a notation in the signature. They
are independent of each other. All four cases are possible.

You (as most people) have not understood how mainkey, user IDs and subkeys are
related. And it seems that I haven't figured out yet how to explain that well.
Both subkeys and user IDs are related to a mainkey. In this sense user IDs and
subkeys are on the same level. There is no such thing as a subkey user ID or a
user ID subkey. User IDs are just "names" for a mainkey. You can add and
remove user IDs and subkeys. They do not affect the other group.
