As you can see there are implications for how you configure the find with the or option.
...
The reason for above single item output is "operator precedence". man find:
Quote:
Operators
Operators join together the other items within the expression. They include for example -o (meaning logical OR) and -a (meaning logical AND). Where an operator is missing, -a is assumed.
.
.
.
Please note that -a when specified implicitly (for example by two tests appearing without an explicit operator between them) or explicitly has higher precedence than -o. This means that find . -name afile -o -name bfile -print will never print afile.
So above command reads find / -name a.txt -o \(-name A.txt -printf '%h\n' \) as (implied) -a precedes -o. Run
Code:
$ find  \( -name a.txt -o -name A.txt \) -printf '%f\n'
A.txt
a.txt

to overcome the problem.
