 cgame prediction will predict a client's own position all the way up to

 postition sent in the most recent snapshot.

 This allows player X to essentially "move through" the position of player Y
 when player X's cmd is processed with Pmove() on the server.  This is because
 player Y was clipping player X's Pmove() on his client, but when the same
 cmd is processed with Pmove on the server it is not clipped.

 Long story short (too late): don't use unlagged positions for players who
 were blocking this player X's client-side Pmove().  This makes the assumption
 that if player X's movement was blocked in the client he's going to still
 be up against player Y when the Pmove() is run on the server with the
 same cmd.
