The only thing we could think of was that sort of scenario that could possibly be valid... but without the original poster coming back and describing more who's to say? You don't need to resolve like that in the event of a true point to point link where you can direct traffic down it (think serial WAN) and the network layer type of traffic (IP or otherwise... much less specific subnets) doesn't actually matter... but that didn't seem to be what the OP was talking about unless in his attempt to generalise and disguise his network layout he hid that inadvertently. For an IP packet to be routed though it does indeed require resolving a gateway on the local link for that to be routed through...
