The same reason why anyone makes a bullish bet with a call spread. You don't mean to tell people there are only some ways to make trades now are you?
In the quote you quoted, there was no synthetic call spread. Just a synthetic call.
The synthetic call spread will be in my latter post where I described doing a protective put and selling a call also.
In any case, actually, the difference between doing a call spread and the situation he is in, is that he is now sitting on cap gains already. Which means the position he puts on is free. Someone who goes out and does a debit bull call spread spends money and risks that. He risks nothing relative to his initial capital. Further, OP seems to want to obtain yield by rolling calls, with a mildly bullish sentiment and expectation that DDD continues an upward trend.
He mentioned a CC. You read a book and offered a collar. Great, but absolutely pointless. He loses a bit below $40 and has maybe a buck in credit on the 3-way simply due to gains. So stop offering advice where you shouldn't. Mildly bullish? That's what you get from his posts?
The 25D reversal is $1.20 puts over calls. So yeah, tell him to buy some puts.
