Is it possible in BEM to use the same modifier for a block and an element?

Question

BEM

Can you please tell me how to correctly lay out such blocks according to BEM:
There are blocks of the same type, they differ only in the mutual arrangement of elements, as in the example:
https://jsfiddle.net/b19chkdf/
I made a modifier for each block block - block_dir_row and block_dir_column. The problem is that some elements (.block__title) should have different margins, in the attached fiddle - 2 and 20 pixels. According to BEM, the external geometry is set through the parent block. But they have the same parent block. So far, I've done this: I've given them the same modifiers as the parents, and made indents through them (see fiddle). Is it correct?

Answer 1

The block name already looks strange, but no
one forbids the use of css nesting

.block__dir-row  .block__title {}
.block__dir-col  .block__title {}

imo it will be so

/* .dir-row */  .dir-row__title {}
/* .dir-col */  .dir-col__title {}
