sure, the default behaviour. Because the system don't know
what the runit should be set to. To the xunit or to the yunit.
\pscircle takes only the runit into account. Compare

\begin{psgraph}[ticks=x,labels=x,arrowscale=1.5]{->}(0,0)(-1.1,-1.1)(1.2,1.2){7.5cm}{5cm}
\makeatletter
\pscircle[runit=\psxunit]{1}
\pscircle[runit=\psyunit]{1}
\end{psgraph}

Only when the x and y axis have the same units, it makes sense to
set the runit by the system.

For your example simply set \psset{runit=\psxunit} inside the
psgraph environment should help.
