It’s really interesting to me that the same moves in a het manga would feel so gross to me, like “Ew she’s pressing her boobs against him, yuck! Stop that!” But when it happens to Tsukushi, it feels so sweet and precious. I think just being able to imagine such a situation happening to me as a woman… “Yes, flirty scenes in a changing room are entirely acceptable. Please proceed.”
This doesn't apply for every Het (bleh!) manga but at least in this case it's something friendly (two girls appraising looks in changing room) being turned by one person to be flirty. If a het couple got into the same changing room, it'd be pretty suspicious and tense from the jump.
Similar things toe the line of flirty and comedic, like when the little sister said 'too late, she's mine', you wouldn't normally expect that, so it's funny...but because the two MCs are a romantic interest, and it's yuri, then the big sister felt that anxiety/jealousy from that otherwise comedic moment.
