I thing the “safe” monicker is still warranted.

It’s called marketing and brand recognition. Most people won’t care it’s not a literal description of how it works, but they will have heard of MagSafe before and get the general idea.

In my experience MagSafe never did that, so it’s likely to be the same on the iPhone as on the Macbooks. Most times when I tripped over the cable, it pulled the cable in a straight line. Unfortunately I can lift my Macbook with the MagSafe cable by pulling in a straight line, so it never actually broke apart the way it was intended. Also unfortunately, it breaks apart very easily if you push up or down, which happens frequently when the laptop is sitting on my lap.

So it would unplug itself constantly in normal use, but still pull the Macbook off the table when I tripped on the cable. It’s still better than nothing, but in my experience MagSafe never worked the way it was advertised. Especially as the Macbooks got lighter.
