does this allow staking for smaller amount of coins?
Yes. But people with more coins will have a significant advantage, and during the latest round of testing it became clear that that advantage becomes more pronounced as the week progresses. The more coins you have, the more weight you have, the more weight you have, well... weight in staking is basically your hashrate. So the more you have, the easier it will be.
With that said, people with small numbers of coins ( on the order of .01 ) will be able to stake, it will just be very very difficult to do so.
