This has no effect because the strut for the pagenumber text effects all 
entries in the footer area.

The following example to demonstrates this (line 2):

\starttext

\ruledhbox to \hsize{\hbox{A}\hss\hbox{B}}

\ruledhbox to \hsize{\hbox{\strut A}\hss\hbox{B}}

\ruledhbox to \hsize{\hbox{Q}\hss\hbox{B}}

\ruledhbox to \hsize{\hbox{\smash[d]{Q}}\hss\hbox{B}}

\stoptext

\setupfootertexts[{Page \pagenumber\ of \goto{\lastpagenumber}[lastpage]}]

\setupfootertexts
   [margin]
   []
   [{\offset[y=\strutdp]{\externalfigure[logo.png][factor=max]}}]
   []
   [{\offset[y=\strutdp]{\externalfigure[logo.png][factor=max]}}]


or


\setupfooter[strut=no]

\setupfootertexts[\undepthed{Page \pagenumber\ of 
\goto{\lastpagenumber}[lastpage]}]

\setupfootertexts
   [margin]
   []
   [{\externalfigure[logo.png][factor=max]}]
   []
   [{\externalfigure[logo.png][factor=max]}]


or


\setupfooter[strut=no]

\setupfootertexts[{\framed[frame=off,offset=0pt]{Page \pagenumber\ of 
\goto{\lastpagenumber}[lastpage]}}]

\setupfootertexts
   [margin]
   []
   [{\externalfigure[logo.png][factor=max]}]
   []
   [{\externalfigure[logo.png][factor=max]}]
