First up, I'm not arguing against the fact that there are many many managers, bosses, directors and CEOs that use emotional manipulation to blackmail employees to do their bidding even though on paper they claim differently. They give it all sorts of names to make you believe this behaviour is okay. The most damaging use of emotive language makes you feel crazy for feeling the way you feel. This invalidation of your experience, of your feelings, is pulled straight out of the narcissist's playbook and it has a name - it's called gaslighting. Making you feel crazy and invalidating you for feeling the way you do. "If you loved this job, you'd do this for me. If you don't do this for me, you can't possibly love this job." Anyone who has escaped an emotionally abusive relationship will attest to how damaging this one technique is. It's often the tool of choice for a narcissist to maintain emotional control of their target.
It's tough to spot because usually the people at the top got there by being charismatic and motivational. They're charming and make you want to follow them... the same way they treat their partners to get them into a relationship before they invalidate them and make them feel crazy to keep control of them and keep them from leaving. The language they're using to make you follow them is manipulation and is also another tool lifted directly from the narcissist's playbook. Beware of the way people make you feel to get you to play along. When you start to feel like your feelings are crazy and that you feel guilty for not wanting to play along, chances are you're being manipulated using these tools.

Secondly, the first part of the statement Ma made, given my own experience is, to an extent, true: "if you love your job, 12 hours is not very long."
I tend to agree that if you're occupied by something you love to do or are fascinated by, 12 hours doesn't seem very long. My experience has been that it tends to go by in the blink of an eye. This statement can stand alone without any implication. I frequently work for 12-18 hours straight without even realizing I've done it and then wonder how I didn't even notice it had got dark and I've missed dinner.
However, the opposing statement that if you don't work 12 hours, you don't love your job just isn't true in my experience. There are days, honestly, where I'm fairly apathetic towards work and I struggle to sit in front of my computer for even an hour. This doesn't mean I don't love my job. It just means I don't love what needs to be done right now.
Just because all cats are mammals does not mean that all mammals are cats.
