The second color comes free only once you've proven you can pay for it. The blue mana is unconditional: this taps for it on turn one, no questions asked. The green demands a Forest or Island already on the battlefield, which inverts the usual promise of a dual land. It fixes best when you least need fixing, on turns three or four when a basic or two has landed, and offers the least when a curve is most fragile. That inversion is the point. A land that entered untapped and fixed both colors immediately would sit strictly above the tapland compromises decks have tolerated for years, so the design borrows a conditional-activation frame to sell an untapped surface at a hidden cost: it strands you as an off-color source when your opening hand is monochrome green, and it rewards the natural basic-heavy manabase rather than punishing it. Compare the older gain-lands and check-lands, which gate their untapped entry or their painless tap on lands you already control; this pushes that logic onto the activated ability itself instead of the enters-the-battlefield step, so the land is always untapped but not always both colors. It is fixing that scales with how developed your board already is, which makes it a smoother top-of-curve draw than an opener.
