Sorry for silly question. I'd like to know if mentioned rules catches

It's not a silly question. All of the TO_EQ_FROM rules compare the full
email address.
In theory I could it by self, it's only one line of code:) But I'm not
so good in regexp to do it.
These rules compare the All pseudo-header since we want to check whether
two different headers contain the same value.
One is for the case where the From: header precedes the To: header. This
is the simpler case. It matches and captures the email address that
appears in the From: header. (Note that the ":addr" option isn't available
for the All pseudo-header so we need to pick out the address part
explicitly.) We then look for the captured string in the To: header.
The other is for the reverse, where the To: header precedes the From:
header. Since the To: header can contain multiple addresses, this one is
less optimal, but it essentially does the same thing: matches and captures
the (first) email address in the To: header and looks for that string in
the From: header.
One possible improvement would be to add a third version that gets the
envelope recipient address in a Received: header, similar to what
__SUBJ_HAS_TO_2 does, and checks for that in the From: header. I will
probably add that shortly.
If you wanted to compare parts of the address you'd have to modify the
part that matches the address; for example to match just the username part
you'd change the capture expression from ([^\n\s>]+) to ([^\s\n>\@]+) and
the match expression from \1[>,\s\n] to \1[\@]
