Two targets with no dependencies

Consider the following makefile:

TARGET=fmake
TARGET2=test_second
fmake: $(TARGET2).c foo.c\
    $(TARGET).c test.h clean
    $(CC) -o $(TARGET) $(TARGET).c foo.c
    $(CC) -o $(TARGET2) $(TARGET2).c
foo.c: 
    echo Some text
clean:
    rm -f fmake test_second
CC=$(VAR2)
VAR2=gcc

After the make bash command the following display

rm -f fmake test_second
gcc -o fmake fmake.c foo.c
gcc -o test_second test_second.c

As said here foo.c doesn't processed because there is no dependencies for this target. But both foo.c and clean have no dependencies, but clean is processed. Why?

Because a file called foo.c exists, whereas no file called clean exists. So Make thinks that one needs to be made. Note that clean should really be declared as a phony target.
