What is the purpose of this code in _embed_clip_tiles method?

[Shiva-Gantha]

What is the use or purpose of the following lines, which is apparently copying the last column and row of the embedding matrix and repeating it?
clip_embeds = torch.concat((clip_embeds, clip_embeds[:, [-1], :]), dim=1)
clip_embeds = torch.concat((clip_embeds, clip_embeds[[-1], :, :]), dim=0)

@Shiva-Gantha Hello, have you figured out the purpose of these 2 lines? I am wondering why where the last column and row of clip feature cloned. Observed same thing while working with LEGAUSSIANS and came here
