Only the content is considered for pooling, so you would only have one
copy even if the names are different. The metadata (timestamp, owner,
permissions, etc.) are stored separately.

They would be considered different during the transport phase. Rsync
would figure out that the content matched and only exchange a few block
checksums - the other transports would send a full copy.

That's pretty much the way the pooling mechanism works, mapping the
pooled filename to a hash of some amount of content with a way to handle
collisions.
