Fair enough. I didn't realise that.
All I can see is by moving the Lakeside from 2nd to 9th it means Eastbourne can use Wood. However Lakeside are missing Bowtell on both dates, so it doesn't benefit them. Equally Mildenhall wouldn't want the 2nd as they'd miss Mountain. It could've been Mildenhall and the Warriors on the 9th though I guess which would mean 2 full strength teams on the 9th but Eastbourne missing Wood against Lakeside. It looks to me like Eastbourne want a full strength team against the strongest opposition.
