Because that's the way it is. I suppose it could be seen as a bug, but there are reasonable enough workarounds.
If you make a post and then another post, and then want to delete the initial post, copy the most recent post - then delete it. Then, provided you haven't timed out, delete the second post. Then paste the more recent and re-post it.

I've definitely used that msg delete workaround before - maybe it's a mapmaker thing. ;)
