I am confused why this powerpoint slight says 'sideways overlap... leads to a p-bonding MO AND a p*-antibonding MO.'

Isn't it one or the other? Why does it say AND? The orbitals can't have descrutive and constructive interaction at the same time right?

The sideways overlap of two parallel p orbitals leads to a
p-bonding MO and a p*-antibonding MO. A pi (p) bond is not
as strong as most sigma bonds.
