If two people have different haplogroups their most recent common
ancestor (MRCA) lived at least several thousand years ago. With some
haplogroup pairs the MRCA may reach back 60,000 years or more, to the
first human migration out of Africa. I think you'd say they are not

Keep in mind though that the Y-DNA test tells you only about your
direct paternal ancestry, i.e. your father's father's ..... father.
You could have a first cousin on your mother's side, for example, who
is in a different Y haplogroup.
