Apologies for not following this thread.

If the question is general, asking whether the Customize UI
ever has more than one button on a line, the answer is yes.

Any :type of (repeat sexp), for example, has both INS and DEL
buttons on the same line.  E.g. `auto-coding-functions'.

And of course the buttons after "Operate on all..." are on
the same line.
