I agree with you 100% and I want to highlight how weird that behavior is.

First you need to analyze an ad. Then you need to ignore that she has a brand and marketing 101 is that ad needs to fit the brand. Then you need to feel like you can make place for your partner to shine. Only then you can come to these poorly thought-out conclusions.

What it really is:

She takes photos that fits her branding. It is a play on “behind every great man is a great woman…” Highlighting that the greatness of a woman can be her strength/power and the greatness of a man can be their love and care.

What they read, “man behind woman, man take care of children, weak”. How insecure is that?

It is a loving supportive message to men and women and they read it like that.
