If in the "Rule" pane of a filter, you put

String    Location    Presence
A         header-Y    Yes
B         header-X    Yes

then the relationship is "And".

This can't be done without making use of the "Alternative" pane,
like this:

The "Rule" pane:

String    Location    Presence
A         header-Y    Yes

The "Alternative" pane:

String    Location    Presence
B         header-X    Yes

All rule "sets" in the alternative pane are, well, alternatives.
I.e., their relationship with one another, which is the same as
their relationship with the only rule set in the "Rule" pane, is
"OR". IOW, inside a rule set, the conditions are linked with "AND",
while rule sets are linked with "OR".

The only way to use "OR" in a rule set is the pipe character "|". It
can be used only when the two (or more) conditions are checking
different strings in the same header field, like:

String    Location    Presence
A|B       header-X    Yes

which instructs TB to find "A" or "B" in header-X.

The FAQ (http://www.marckp.redhotant.com/thebat/faq.html) has a "How
do I" section which provides an in-depth guide to the filtering
capabilities of TB.

Use the "Kludges", like

String           Location    Presence
Reply-to=A       Kludges     Yes

IOW, when searching in Kludges, you may include the header field
identifier.
