Explanation

:a;                                # Assign the input to the "accumulator"
   7,                              # Yields [0 1 2 3 4 5 6]
     {                          }, # Keep all that full fill this condition
                                   # Item = current item
                                   # ac = accumulator
      a"sdrmflsooeiaail"           # Stack: <item> <ac> "sdrmflsooeiaail"
                        @          # Stack: <ac> "sdrmflsooeiaail" <item>
                         >         # The slice begins at the current item
                          7%       # With a step of 7
                            /      # Try to split the input by the sliced item
                             ,2=   # Is the slice was successful?

Explanation

In fact the whole thing is quite simple.

:a; # Preserve the input
"doremifalasi"2/ # Split the string into chunks of 2
["sol"]+ # Add the outlier into the list
{a\/,2=}, # Filter out all items that aren't in the input
# Empty list is falsy. Nonempty list is truthy.
