It's not quite right: different OSD approved licenses have different
terms with regard to selective distribution. Under the GPL, for instance,
you can selectively distribute if you send the source code with the
object code, but if you don't, you have to publish the source.

Under the OVPL, you can selectively distribute, but the ID has the
right to ask for your mods. He can only use them in a proprietary
version if he publishes them and makes them available to everyone.

You are correct that if you do not distribute, 3.3 does not come into
play at all (pace arguments re external deployment)
