How is that confirmation of anything?

The economics will rule.

Perhaps they want to make some money by seeing how many LTC traders will dump back to them. Sell high, buy low is what they doing.

Or other chess moves going on behind the scenes.

I've read the F2Pool long ago said they would support SegWit on Litecoin, but just in any definite timeframe.

Of course they have to maximize their profits and strategy along the way.
