When you reverse a oneway=yes (or oneway=1) in JOSM it will pop up a
dialog asking you if you'd like to change the oneway tag so that it's
consistent with what what the combination of the way direction /
oneway attribute meant previously.

Since you answered yes to this JOSM changed oneway=1 to oneway=-1,
which means "The direction of this the way is opposite to the way
direction".

You can fix this by changing oneway=-1 to oneway=yes.
