It's interpreted as a path.  I.e., with

/usr/bin:/bin

and point over the first bit, it returns "/usr/bin".  And empty
strings are valid directories in paths, and means "the current
directory".

So what it's doing is consistent, but perhaps surprising.  We could
change it to disregard the path interpretation if the string starts with
":", because that will be correct in the vast majority of the cases.

It more DWIM, but the ffap functions are already pretty DWIM, so I'm in
favour.  Anybody else got an opinion?
