Thats a job they invented biscuits for, prevents up/down movement, but
allows lateral movement. Very strong as well.

Why should there be any lateral movement? It's a parallel long-grain
joint.

By lateral movement I meant that if you are joining two boards along their
long edges, you have movement along those long edges IYSWIM. So you could
get the ends to line up for example.

Isn't that lateral?

Longitudinal.

I do that with a pencil mark (crudely), then trim the ends to length
_after_ I've jointed, joined and thicknessed them. I like long ends
left on boards before jointing, if there's any snipe caused by the
jointer, chances are that it's on a bit I'm going to trim off anyway.
