Well, then you are doing software raid10, even though not with md. :-)
But yes, the above description is ambiguous, and indeed lvm can
do striping and mirroring (could before md was invented, or even
before Linux ever got either).
I once compared raid0 with md vs. lvm striping (being used with
the latter from hp-ux), and decided to go with the former.
There wasn't much difference in speed as I recall, but md allowed
making bootable raid1 and it seemed better supported in Linux.
