B777 Wing Anti-Ice

Hi Guys,

Can the wing anti-ice be used with the wing slats extended or not?

It also states this in the FCOM...

Automatic wing anti–icing operation is inhibited when all the following conditions exist:
• TAKEOFF mode is selected, and
• wing icing conditions exist, and
• less than 10 minutes has elapsed after liftoff

Why is this? The second condition has me confused
Also, if the WAI is selected to on during the inhibited period, does it override the statement?

Thank you
