8 – Field name shared among entity types?

I have always separated my field names by entity. e.g.

field_paragraph_h2 or field_content_h2,

but when you look at the configuration, the fields are also designated by their entity type.

field.field.paragraph.paragraph_type.field_paragraph_h2 or field.field.node.content_type.field_content_h2

I'm sure using only field_h2 for both entity type field names, or are there instances with Drupal where this can be problematic?

e.g.

field.field.paragraph.paragraph_type.field_h2 or field.field.node.content_type.field_h2
