well, yes; but I wouldn't say that it has gathered a "very different" meaning.
W3 would have it thus:
1) to gather together scattered remainder of grain or other produce left by reapers
2) to gather together, pick up, or acquire information bit by bit from some source

to me, this is just another transferral, or generalization -- I've never had an opportunity to use it in the original sense, just as with decimate.
