Investments in WTI crude oil futures contracts are subject to position
accountability levels and position limits set by the listing exchange for such
contracts – the New York Mercantile Exchange or “NYMEX.” On May 1, 2020
the Funds received notice from the exchange directing the Funds to not
exceed an exchange-designated position accountability level in the September
2020 WTI crude oil futures contracts.
In response to this notice, and to help manage the impact of significant
volatility and other market conditions, each Oil Fund intends to transition
1/3 of its portfolio exposure from the September 2020 WTI crude oil futures
contract into exposure to the December 2020 WTI crude oil futures contract by
the close of business on Monday, May 4, 2020. At such time, each Fund expects
to have approximately 2/3 of its portfolio exposed to the September
2020 WTI crude oil futures contract and approximately 1/3 of its portfolio
exposed to the December 2020 crude oil futures contract.

大意是现在UCO有1/3是12月的仓，2/3在9月的仓
不过里面提到基金收到NYMEX的通知不要"EXCEED"超过9月
既然不要超过9月为什么又要转1/3到12月呢?
有高手可以解释一下吗?谢谢
