No, you haven't been misled.  It's understandable, with the way Intel has 
decided to make so many 486 variants so as to confuse prospective 
processor cloners as to which 486 they should emulate. The 486 sx is 
essentially a 486 dx with the math processor removed.  To confuse things 
even further the 487sx is a complete processor/coprocessor combination 
which takes over all processing functions from the 486sx chip, as is the 
new OverDrive chip.
