Hans,
Sorry, but I can't really answer your question, but here is my guess.
I guess this is something like a Database protection. The first spoke commes up
and builds an adjancency with the Hub Router. LSP's are exchanged, and a DR is
elected. After that, the Database must be equal on both routers. Now if the
second spoke comes up the Hub router gets broadcast net LSP's from the new spok
e
stating only one adjancency (with the Hub). From the other spoke it gets LSP's
also only stating that there is one adjancency (with the Hub). I think to avoid
a Database corruption the Hub router does not accept the LSA's from the second
Spoke until all router on the broadcast net report the same adjacencies. But
again, this is just a guess from me, and I did not test it in the Lab.
