Nah, they are distinct. Like you said, the dino hunting stuff was an example flung out there occasionally, a fun possibility.
The Legs stuff had much firmer language used on the bigger bones of it ('You will be able to walk around a spaceport' etc), and those bigger bones are written into financial purchases like the LEP. Pretty distinct.
None of it means it's all nailed on to be delivered, for sure, but the language on the bigger stuff is certainly 'promise' tier in those examples, and borderline contractual regarding LEP sale info.
Trying to cast this stuff as 'Yeah that'd be cool' pronouncements is downplaying way, way too much.
They also said any expansions relied on financial viability and technical possibility. They already dropped the season model and lowered the price of Horizons so financial viability may be less than they planned for or take longer to achieve, they also delayed squadron carriers so technical feasibility may be hitting issues.
Go read kickstarter clearly explaining that plans always change and the end product might not be exactly as described. LEP's and kickstarters are always a gamble, kickstarter LEP's doubly so.
