basically a secondary alkene is an alkene where the double bond between carbon atoms has two alkyl group on the carbon attached

You are not "using" an alkene, you are producing an alkene by elimination. It should say an "asymmetrical secondary haloalkane".
What it is trying to say is that you could have the bromine in such a position that elimination could produce two different alkenes.
CH3CHBrCH2CH3 can make both CH2=CHCH2CH3 and CH3CH=CHCH3

The "Tip" as stated is nonsense - probably a typo.

I see. I understand but I now fear that my source material is unreliable.

Sorry for late reply - agree with charco, it’s an alkene/alkane typo. I have looked at that section in the book and all the examples are an alkane (actually all halogenoalkanes) undergoing nucleophilic substitution or elimination (which is the point of that section).
The example at the end of the “Tip” is describing an alkane to alkene reaction, which further confirms the typo.

I have yet to read a chemistry book that was 100% without typos.
