Correct, the green markers were originally set up at 110th mile intervals. On 2 way roads they alternate sides on one way, divided highways (IE. freeways) they are posted on both sides. We do not refer to them as mile markers rather as reference markers. We felt no reason to change these to metric when we converted because the numbers are only consider a location or reference.
Generally signs are posted to the nearest 1/2 mile or 1/4 mile. Anything lest than 1000 ft. is supposed to be sated as "ahead" or with no distance. There are exceptions and the 2/10 miles sign was probably one of those or an older sign.

Same goes for I-81 in NY and Pennsylvania. In PA they're marked off a whole number that is one decimal place larger than the mile number, i.e. mile 215.7 is shown as 2157, etc. At one of the NY highway greeting centers, I read a nice blurb on the 10ths markers, which are meant to be there for safety's sake--one can provide a very accurate location in case of an emergency. Around Rochester, NY, at least, there is a tendency to display short distances to exits in 10ths of a mile (Exit 2/10 mile).
