Different filesystems use different parts of the disk, this is a fact
of life. For any and all re-use of disks, I tend to recommend to zero
out as much as you can wait for before putting a new OS on a disk.
After having dealt with the weird linuxisms that come up when not
properly wiping your disk not too long ago, my believe in this
approach has been greatly reaffirmed.
(in some cases, linux can put some metadata on either or both the
beginning and end of a disk - wiping only the first few megs leaves
the data at the end for great "fun" but not much profit upon
reinstalling).
I've not had much issues in this area with OpenBSD myself, but then I
tend to not mix different filesystems on my OpenBSD disks anyway (my
machines usually just run one OS). It still doesn't hurt to wipe the
disk though.
