Correct. The first backslash escapes from the tcl interpreter. The  
next backslash espaces from the regular expression engine.

reinplace "s|\\.\\./lib/${name}|\\.\\./lib/${distname}|g"} ${destroot} 
${findITKbranch}


If you don't need any variables in your regular expression, you can  
enclose it in {brackets} instead of "quotes" and then you only need a  
single level of escaping. But you are using variables name and  
distname so you need quotes and thus both levels of escaping.
