It's a first, crucial gap in the armor you're making.
By making straight boys love eachother, you're opening a route where they can get positive emotional feedback thinking about boys, kissing boys, frotting with boys, ect.
This lets them build the mental pattern of thinking about boys and feeling good, which can slowly start spreading to other boys. If kissing THIS boy makes his heart pound and his penis feel hard and good, and makes his head fuzzy, then maybe kissing another boy might, too. This is crucial, because this leads to the first independent exploration of boys; the love with the first boy was induced, but the inevitable curiosity about if it will feel good with other boys is entirely organic.
By making a boy love another boy, you are planting the seed of gay in his heart, that can grow and blossom under his own guidance.
