I too have worked at organizations that have been configured like this. I speculate that pressure on the limited IPv4 allocations has caused many places that had previously been configured with large public IP blocks, to sell sub-allocations, for profit. NAT certainly does enable this practice but isn't the root cause. Sell those IPv4 blocks for $$$ -- who needs their laptop getting a public IPv4 address anyway?
It's weird how much NAT has changed the thinking about network organization -- if you have the addresses you should get into the IPv6 state of mind -- publicly address all the things!
Now if your org picked 97/98 arbitrarily without actually owning the addresses relying on the fact that you wouldn't actually get routed any public traffic then that's a different story.
