Maybe yes. Maybe no. It's a problem in definition.
What can be said is that, in addition to whatever attention-seeking behavior your cat displays towards you, if he/she spends a lot of time with his/her back towards you — as in every Kliban cartoon — he/she is demonstrating complete trust that you've "got his/her six" and will protect him/her from attack from behind — just like mommy would do.
Rationale:
Felids generally attack prey from behind and therefore consider themselves to be vulnerable in the same way. The domestic cat often demonstrates this hard-wired behavior by hiding/sleeping in enclosures such as grocery bags and boxes with one opening (ie, protected in the back and on the sides) and facing out through the opening.
Similarly, if your cat spends a lot of time on his/her back, displaying his/her underside to you, he/she is certain that you will not attack and eviscerate him/her — as he/she might attempt with adversaries and prey.
So, your cat accepts you as his/her friend and protector, even if love is not in the air. It probably doesn't get much better than that. 😊
