It's the opposite, looks like I misnamed the columns. I've posted a new version of the doc with the correct column names to the same address, thanks for noticing!

They both get Truck removed (see above with the switched column names).

The change would be from these:
	network=US:OH:Truck,	ref=38,	modifier=Truck
	network=US:AL,	ref=47 Truck,	modifier=

…to these:
	network=US:OH,	ref=38,	modifier=Truck
	network=US:AL,	ref=47,	modifier=Truck

I've been in touch with them via messages on the OSM.org site, not sure how many are subscribers here.
