There cannot be two addresses!
Do you ever heard of compressed/ uncompressed addresses???
Pleased read this:

No offence! But the link you posted not even contains the term "compressed".
The two addresses above have private key 3. Right? At least this is claimed.
But neither looks "compressed". Both look like the legacy address format. And the algorithm for deriving such an address from a private key is well known and is clearly defined. Also in the year 2015.
If both addresses were two sides of the same coin, how do I convert the one address to the other? (rhetoric question)
Last but not least, using a blockexplorer, it is easy to see that, e.g., address (0x483)
was never used, but (also 0x483)
was used.
I do not deny, that 1PgQVLmst3Z314JrQn5TNiys8Hc38TcXJu has a private key since the funds were moved. But it is not 3. At least not to my knowledge.
Edit: This page offers a private key to address converter (but do not enter your real private keys):
