I think that the reason is that with -mlstyle- you set the
style of the line and not the linepattern. For the difference
compare -help linestyle- with -help linepatternstyle-. 

One way that I often use to "push back" some too dominant 
graphical element is to make it grey. To use your example:

*------------------ begin example --------------------
sysuse auto, clear
twoway scatter price mpg [aw=displacement], ///
       msymbol(Oh) mlcolor(gs8) 
*------------------- end example ----------------------

Hope this helps,
