This get interpreted as :
cylinder{<0, 0-1.25> <0,0,1.25> 1}

You can ignore the comas, but only in unambiguous cases. Whenever you 
have a negative value, the coma is mandatory in front of it.

There was a time, prior to version 3.0, where the space was a hard 
separator and when your way of defining the vector was interpreted as 
<0,0,-1.25>. It's been over 30 years that it's no longer the case.
