That doesn't make any sense

Don't expect it to make sense. Tooling up to change the track cranks for the tiny market probably wouldn't wash with the accountants. If you want a sensible reason, I think the problem was mostly on MTB cranks which suffer impact loads from people jumping off stuff, which is a bit less likely on a track bike, and it's also possible that the DA cranks are made from a different (stronger) alloy than LX MTB cranks which, combined with closer tolerances, might well be enough to ensure that they don't get track cranks back with stripped splines very often.
