Could someone clarify when there is a JE to record the purchase of an option and when there's a memorandom only/no JE?

I've copied and pasted 2 different illustrations from Wiley that seem conradictory to eachother and are confusing me.

Per illustration 1, if you don't even record via JE the purchase of a put option for a fair value hedge, why would you record an increase in the value of the put option later?

 EX 1

Hayward is exposed to the risk that the price of the Sonoma stock will decline. To hedge this risk, on January 2, 2009, Hayward purchases a put option on 100 shares of Sonoma stock and designates the option as a fair value hedge. This put option (which expires in two years) gives Hayward the option to sell Sonoma shares at a price of $125. What entry is required on January 2, 2009 to recognize the put option?

A memorandum entry only. Since the exercise price equals the current market price, no journal entry is necessary. 

At December 31, 2009, the price of the Sonoma shares has declined to $120 per share. Hayward records the following entry for the Sonoma investment, and to recognize the increase in value of the put option.

       Unrealized Holding Gain or Loss—Income 500 
               Security Fair Value Adjustment (AFS)   500

       Put Option 500 
               Unrealized Holding Gain or Loss—Income   500  

EX 2

On January 2, 2008, Jones Company purchases a call option for $300 on Merchant common stock. The call option gives Jones the option to buy 1,000 shares of Merchant at a strike price of $50 per share. The market price of a Merchant share is $50 on January 2, 2008 (the intrinsic value is therefore $0). On March 31, 2008, the market price for Merchant stock is $53 per share, and the time value of the option is $200.
 Call Option 300
              Cash  300

Then to record the G/L of the call option and the securities:
 
Unrealized Gain or Loss—Income 100 
           Call Option ($300 – $200)   100

Call Option (1,000 X $3)  3,000 
           Unrealized Gain or Loss-Income    3,000
