Repels and the pike square

[Taqwus]

Units don't get a repel benefit from being in the same square as a unit with a long weapon, correct? The manual at least seems to indicate that it's only the target's weapon that matters, not anybody else's.

For instance, if one mixed pikes and crossbows in the same squad, and a knight attacks one of the crossbowmen who shares the square with two pikemen -- the pikes do not repel the knight?
