Matching addresses on 3 blockchains

[missfox]

Let's say you have bitcoins on the legacy chain, (BTCaddress1)

As a result, you got whatever amount of bitcoins held there in the BCash chain, (BTCaddress2)

Finally, you didn't move your coins from there, come November and you get whatever amounts of bitcoins held on BTCaddress1 in 2x's chain (BTCaddress3).

Notice that BTCaddress1, BTCaddress2 and BTCaddress3 are all the same address because the jackasses doing forks don't even bother in having their own address formats.

Anyway, my question is... does this pose any risk when I try to access one of them? what would be the correct way to access BCash and 2x without screwing up in the process? im not sure since it's a triple match...
